C++ geometry [for game projects and similar]

15:17 By Usman Shery

Hi.
Let's just call it a graphics function blog thoe i just know 2 or 3 of them but they'll be enough for simple drawing.

This will require gotoxy function which is mentioned in a blog from Umair Sajid. The recap is as follow:
________________________________________________________________
#include <iostream>
#include <windows.h>

void gotoxy ( int , int ); //prototype
{main function and stuff}
void gotoxy(int x,int y) //header. with x and y as coordinates to where cursor goes
{
HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
//output handle to be defined for function
COORD coordinates;
//COORD is a data type of windows.h header to store 2D graphic position's coordinates.
coordinates.X = x;
//save x coordinate value into the COORD structure's data type
coordinates.Y = y;
//similarly for y axis coordinate
SetConsoleCursorPosition( hOut , coordinates );
//finaly the function which set's the position of the cursor that you
gave
}
define it and then you are good to go for the graphics functions
=======================================================================

Simple lines:

To understand this, just look up to coordinates of a simple line:

They change in a simple manner:

x,y

x+1,y

x+2,y

x+3,y

x+4,y

x+5,y

Here is a more understandable form:

x,y

++x,y

so here is the functions:

________________________________________________________________________

1. Horizontal line:

void horizontal_line(int , int , int);

void horizontal_line(int x, int y, int size)

{

for(int i=0;i<size;i++)

{

gotoxy(x,y);

cout<<char(219);

x++;

}

2. Vertical line:

void vertical_line(int , int , int);

void vertical_line(int x, int y, int size)

{

for(int i=0;i<size;i++)

{

gotoxy(x,y);

cout<<char(219);

y++;

}

=======================================================================

2. Simple squares:

void square(int , int , int , int);

void square( int x, int y, int width, int length )

{

int t_x;

for(int i=0;i<length;i++)

{

t_x=x;

for(int j=0;j<width;j++)

{

gotoxy(t_x,y);

cout<<char(219);

t_x++;

}

y++;

}

=======================================================================

You can also use colours for making it better.

Errors in code are possible as i did'nt made it on compiler so don't think that it won't work. In case of any problem you can email me.

That's all. I hope this'll help ya with simple interfaces. I'll give other methods for circle, hollow square ( completely hollow ) when obviously i need to make them and use them :)

Filing in C++

13:37 By Unknown

Its very irritating to input again and again and best way to avoid it is FILING and it is pretty simple :)

Code:

 #include<iostream.h>
 #include<conio.h>
 #include<fstream.h>
 void main(){

   char name[15];

//---------------- READING FROM  FILE ---------------

ifstream insertion("contries.txt");

cout<<"\t\tReading data from file contries.txt\n\n"<<endl;

   while(insertion>>name)
   {
    cout<<name<<endl;
   }

insertion.close();

//--------------- WRITING IN FILE ------------------

//to clear the data of "data.txt" so that new content overwrites the file

// if u want to append new data to previous file skip the following two lines

ofstream empty("data.txt");

empty.close();

 //writing new data in "data.txt"

cout<<"\t\tWriting following data in file data.txt\n\n"<<endl;

int copyng[]={1995,1996,1997,1998,1999,2000,0,8,7,6};
ofstream burr("data.txt",ios::app);

int n=sizeof(copyng)/sizeof(copyng[0]);     //to find out the size of array in terms of # of elements

   for(int i=0;i<n;i++)
   {
   cout<<copyng[i]<<endl;
   burr<<" "<<copyng[i]; }
   burr.close();
   cout<<"\n\t\tPress any key to exit"<<endl;
   getche();
   }

Hollow Square & Hollow diamond & Hollow Triangle

02:11 By Usman Shery Hollow Square & Hollow diamond & Hollow Triangle , newbie 3 comments

Hollow Square & Hollow diamond & Hollow Triangle

It's basically a request from a student as we go further in loops and functions we need to know more tricks and practise more for these things which eventually leads to good programming;

Basic concept to understand;

Notice if any line of the shape is going to match original filled shape; i.e. in square the first line and last line are filled!
Make sure you know the ration of spaces for hollow part to the number of characters in the corresponding filled space i.e. if your square is of the size of 5x5 so it is going to be 5 characters in a single line; but in hollow shape you are going to print only 2 characters ; the first one and last one no matter how much long line is this; but here in 5 character line the total spaces would be countable as spaces=one side length - 2;

Prepare for the basic shapes looping that will be joined together to make final shape i.e. to make diamond you place 4 triangles together if you ever made it:

Hence by mixing these points you can make logic of this king of shapes.

Basic Hollow looping;

In this kind of looping you have to make sure that ration of lines is safely described to make appropriate loop

Square concept:

int main()
{
int size; //suppose it is 5
cin>>size;
for (int i = 0 ; i < size ; i++ ) //runs 5 times
{
cout << "*" ; //first char
for (int j=2;j<size;j++) //runs 5-2 times
{
cout<<" ";
}
cout << "*" ; //last char
}
return 0;
}

Now here in line 8 you can see that formula which subtracts number of characters from hollow line to make it even to the rest of shape, it could be 5 - 3 or maybe 5-4 required for the program hence the distribution of spaces and loops as well; depending on the shape.

And for first and last line here is simple method:

if ( line 1 || last line ) //mean i==1 or i==size-1 according to loop iteration
{
for ( int a=0;a<size;a++ )
{
cout<< "*" ;
}
cout << endl ; continue ;
}

Put it in main loop Before the space loop so that if first line is being print it would print it and skip the space printing for first and last line.

i guess it is enough for the basic concept and you will be able to make assignment ;; I'll give complete codes after exams;; thanks for reading and for feedback or any questions:

gotoxy() function in c++ by Umair Sajid

21:49 By Umair Sajid

gotoxy() function :

The gotoxy function is used to to move the cursor to a specified location on the screen. Its Just Something Other then just Sequential Execution .It moves the cursor with respect to x axis and y axis. It is very useful when the output is to be displayed at a specified location on the screen.

Working:

The Variable x indicates x-axis. Its Value can be from 0 to 79. The Variable y indicates the y-axis. Its Value can be from 0 to 24.

Program:

#include               // Header Files 
#include               // for getch() function 
#include               
#include             // Necessary when treating consoles  
using namespace std;
void gotoxy (int x, int y)
    {
         COORD coordinates;     // coordinates is declared as COORD
         coordinates.X = x;     // defining x-axis
         coordinates.Y = y;     //defining  y-axis
        SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),coordinates);       
    }
int main()              
{
    int x;
    int y; 
 
    cout<<"Enter x: ";
    cin>>x;
    cout<<"Enter y: ";
    cin>>y;
        
    gotoxy(x,y);     // function call 
    cout<<"C++ Clan Umair Sajid"<<endl;
    getch();
    return EXIT_SUCCESS;
}

Easy Colouring

19:38 By Usman Shery beautify your C++ console programs , c++ , special effect 3 comments

As promissed here is bit easy technique for those colour commands;

Hope you guys understand it :

Theme here is to use funcitons to determin command stuff i.e. how much easy would it be if you only have to type

color(r); //red colour

here is the function that will help you to use colours easily

______________________________________________________________________

HANDLE Output=GetStdHandle(STD_OUTPUT_HANDLE);
void colour(int x)
{SetTextAttribute(Output,x);}

______________________________________________________________________

here if you remember colour codes integers just use them as follows:

colour(10); //green

and if you want to make it runing upon character values you can place switch in it

HANDLE Output=GetStdHandle(STD_OUTPUT_HANDLE);
void colour(char ch)
{
int x;
switch (ch)
{
case 'r': x=12; break; //red
case 'b': x=9; break; //blue
case 'g': x=10; break; //green
case 'a': x=11; break; //aqua
case 'v': x=13; break; //voilet
case 'y': x=14; break; //yellow
case 'w: x=15; break; //white
}
SetTextAttribute(Output,x);
}

now you can call it as this;

colour('r'); //red colour

Play Sound in Your CPP Program

18:48 By Unknown .wav in cpp , Music in cpp , play sound in cpp 3 comments

Till now, all of us have coded C++ programs on the black & white console, some know how to color the text on string.
Lets go a step ahead and introduce sound being played as your program runs.

Interesting, Right?
Yes, you'll have a new effect to add in your code :-)

How to Do?
The amazing sound feature consists of just two lines,
1. The PlaySound function call.
2. The header file that contains this function.

Code:

#include<iostream.h>
#include<conio.h>
#include <string.h>
#include <windows.h>
using namespace std;

int main()
{
PlaySound("file_name.wav",NULL,SND_FILENAME|SND_LOOP);
// PlaySound method is defined in windows.h
// file_name is the name of your sound file in .wav format
getche();
return 0;
}

Note:
Your .wav file should be in the same location as that of ur .cpp file.

More:

For details and possible values of parameters in PlaySound function visit the link below

Include sound in your programs and have FUN
Stay Blessed :-)

Bit Level Manipulation and Programming in C++

13:22 By Unknown Bit Level Manipulation and Programming in C++ , Bit Shift operators , Division in C++ with bitshift operators , Multiplication 8 comments

C++ is a classical language and it allows us to manipulate bits in much better ways. for starter we will learn 2 kind of bit operators namely bit shift operators

Left shift operator: <<

Right shift operator: >>

The left shift operator shifts all bits to left and left most bit(MSB) is dropped/deleted

similarly the right shift operator shifts all bits to right and LSB(right most bit) is dropped

e.g. binary of 2 will be 00000010 which is when shifted to left becomes 00000100 which in decimal is 4
so it also means that shifting to left multiplies by 2 and shifting to right divides by 2.

void main()
{
int castles = 2;
castles = castles<<1; //this will set castles = 4 i.e. 2x2
castles <<=2; //this will left shift by 2 bits and hence castles is now multiplied by 2 two times so it now becomes 16
//you can experiment for your self with these tricks
//PS these are heavily used for masking purposes and files compression as well

Addition of two 2-Dimensional Arrays

13:18 By Unknown 2-D array , addition , c++ , newbie 1 comment

Below is the code that I made to add the elements of a 2-D array.
The 2-dimensional arrays have been previously discussed, what they are and how to initialize them.
http://cppqa.blogspot.com/2013/11/two-dimension-pointers-c.html

For those (like me) who are still confused, think of it like this,
An 1-dimensional array can hold element like this:
[ 1 3 5 7 9] => array1[5]

Whereas a 2-D array will hold elements much like a matrix, like this:
| 2 4 |
| 6 8 | => array2[2][2]
So we get a matix of 2rows and 2 columns.

Now that we have a basic concept of 2-D array, lets go a little further.
The initialization is petty much same as that in the above link. We shall only do the addition of 2-D arrays.

int main()
{
int x[2][2] , y[2][2] , z[2][2];
//for simplicity 2,2 matrix is used, but you can also make a user specified

int i , j , k;

cout<<"enter number for 1st matrix"<<endl; //applying for loop to enter the data

for( i = 0 ; i < 2 ; i++)
for( j = 0 ; j < 2 ; j++)
{
cin>>x[i][j];
}
 
cout<<"enter numbers for 2nd matrix"<<endl;
for( i = 0 ; i < 2 ; i++)
for( j = 0 ; j < 2 ; j++)
{
cin>>y[i][j];
}

for( i = 0 ; i < 2 ; i++)
for( j = 0 ; j < 2 ; j++)
{
z[i][j] = 0;
for( k = 0 ;k < 2 ; k++)
z[i][j]=x[i][j]+y[i][j]; // x + y stored in z
}

cout<<"additon of matrix is"<<endl;   // z is displayed
for( i = 0 ; i < 2 ; i++)
{
for( j = 0 ; j < 2 ; j++)
cout<<z[i][j]<<"\t";
cout<<"\n";
}
getch();
return 0;
}

So here it is a simple program to add two 2-D arrays

Recursive functions

19:30 By Usman Shery

Recursive functions

Recursive functions are way much difficult then simple functions

in a function you place set of commands in a bracket and use it as many time as u want
in recursive functions you make such a function which with the help of other functions and the repetition of it's own body gives you output ; complex but short code.

As compared to recursive function simple function when called runs specific commands inside it's body (could be loop but still simple as for command) it's decision criteria is small or let's say limited.

In recursive function you make some kind of super function which has wide choice of features including that it's body is small.

Definition: When a function calls itself or other functions while execution it is said to be recursive function.

Here is a simple example :

To print a countdown form a digit that user inputs up to '0'

#include <iostream>
using namespace std;
void sample_recursive_function(int N)
{
if (N==0) { cout<<"N"<<endl; }
else { cout<<"N"<<endl; --N; sample_recursive_function(N);}
}
int main()
{
int N;
cout<<"Enter the number: ";
cin>>N;
sample_recursive_function(N);
return 0;
}

Enter the number: 5

4 -

1 ^ --

0 -

Press any key to continue . . . .

In this function there is not much as coding or might say complex coding but it is a complex logic. This is what is difference between these functions.

This function can also call other functions described in this program hence you can generate loop in which more then 1 functions will work with each other to generate desired output;

A -------------> B

^ |

| |

| V

D <------------- C

In this diagram functions are related to each other because when you call one function in another function the control goes to this function and once this function is finished then it will allow for control to go back to main called function..

Here is an example :

int sum(int a , int b ) //f1
{
int c= a+b;
if ( check_type(c) == 1 )
{ return c;}
else
c+=1;
}
int check_type(int x) //f2
{
int check=x;
if ( x%2==0 )
{ return 1;}
if ( c%2!=0 )
{ return 0; }
}

Here f1 is calling f2 to change it's output. A simple recursive function.

Hope you understood the concept of recursive functions; gud luck; Allah HAfiz

Colour Coding in C++

15:37 By Usman Shery

The first time i saw colour in c++ was amazing experience because just black and white stuff is more like old school comparing to modern software and technology. It was hard to find well defined code and definition for colours in c++ language ; took me a while but i got it finally so here is this code in simple language, hope it helps you...

_________________________________________________________________________

To change whole screen colour i.e. foreground (text) and background, it is very simple and easy command.

The header file for this command is : <windows.h>

The command is : system("Colour _ _");

In place of _ _ you have to enter colour combination you want ; first place takes background colour and 2nd place takes foreground colour (text colour) this is list of all colours available for this command:

1_____Blue A______Light Green

2_____Green B______Light Aqua

3_____Aqua C______Light Red

4_____Red D______Light Purple

5_____Purple E______Light Yellow

6_____Yellow F______Bright White

7_____White

8_____Gray

9_____Light Blue

0_____Black

It's not perfact colouring but it is simple to use

#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
system("Color 0A"); // first 0 = black background second A = light green
cout<<"This is my fev. colour combination for this command"<<endl;
return 0;
}

This is my fev. colour combination for this command

Press any key to continue . . .

=========================================================================

The detailed coding

_________________________________________________________________________

To change minor colour i.e. colour of just 1 character so that we can use as much colour combinations ; it comes to this code because command showed above will not allow you to print 2 or more colours in single output combination. This command is not capable of changing whole background so i prefer to select background colour from system command and then change text colour from this code i'm about to share with you guys.

This must be wirten at start of main: HANDLE color=GetStdHandle(STD_OUTPUT_HANDLE);
The header file for this command is : <windows.h>
The command is : SetConsoleTextAttribute(color, _ );

In place of _ you have to enter colour code you want ; there is a brief list of some basic colours for this command:

1_____Blue     10______Light Green
2_____Green   11______Light Aqua
3_____Aqua   12______Light Red
4_____Red   13______Light Purple
5_____Purple 14______Light Yellow
6_____Yellow 15______Bright White
7_____White
8_____Gray
9_____Light Blue
0_____Black

#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
HANDLE color=GetStdHandle(STD_OUTPUT_HANDLE); //just once
SetConsoleTextAttribute(color, 10);
cout<<"This";
SetConsoleTextAttribute(color, 11);
cout<<" is";
SetConsoleTextAttribute(color, 12);
cout<<" a";
SetConsoleTextAttribute(color, 13);
cout<<" colour";
SetConsoleTextAttribute(color, 14);
cout<<" combination"<<endl;
return 0;
}

This is a colour combination

Press any key to continue . . .

But the best thing is that it doesnot stops here at 15 ; you can go up to 300 for different colour combinations for headline your text on your program; enjoy
Like this post then i will tell you how to use 2nd one command very easily like this:
clr( _ );
that's it..@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Ascii Art with C++

15:10 By Unknown ascii art , beautify your C++ console programs , C++ ascii art 3 comments

While posts on shaskaas are going on let me share another tweak with you. As a trademark thingy you can insert your name with ascii art in beginning of your program and this will always impress your teachers. I used star wars theme always for my assignments and you can bet the marks i got :P

We use figglet for generating asscii art Figglet Fonts.

Then i would just cout this text

/**
_    __  .___  ___.      ___      .______      
|  |  |  | |   \/   |     /   \     |   _  \     
|  |  |  | |  \  /  |    /  ^  \    |  |_)  |    
|  |  |  | |  |\/|  |   /  /_\  \   |      /     
|  `--'  | |  |  |  |  /  _____  \  |  |\  \----.
 \______/  |__|  |__| /__/     \__\ | _| `._____|
  
**/

Happy Coding :P

Program that converts ASCII number to character and vice versa By Umair Sajid

12:14 By Umair Sajid

This Program can also be done using if-else structure but switch statement is most appropriate.

#include<iostream> /* Header Files */

#include<stdlib.h>

#include<conio.h>

using namespace std;

int main()

{

int number,option;

char letter;

cout<<"1.Convert ASCII Value to Character "<<endl;

cout<<"2.Convert Character to ASCII Value "<<endl;

cout<<"Enter Your Choice :"; cin>>option;

switch(option)

{

case 1:

cout<<"Enter The Number :";

cin>>number;

cout<<"The Corresponding character is :"<<char(number)<<endl; break;

case 2:

cout<<"Enter The Letter :";

cin>>letter;

cout<<"ASCII Value of the letter is:"<<int(letter)<<endl;

break;

default:

cout<<"*** INVALID OPTION ***";

break;

}

getch();

}
