Bit Level Manipulation and Programming in C++
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: >>

Reverse any Integer without strings
It seems now are a stronger community to write generalized programs for FAST NU as well :)
I am posting a program below which reverses any number with just 1 while loop.
See if it works :P

Input in functions : type of input
We can use functions by 2 methods of input:
input as passing arguments by values [Part 1;]
input as passing arguments by reference [Part 2;]
