C++ program to check for Even Numbers using Bit Manipulation

By Aalok Kumar

Hello programmers, Using Bit Manipulation, I have written a C++ program to check whether a number is Even or Odd in just one line of code.

Bitwise operators are used to working on Bit-level to manipulate Bits.

In my program, the Bitwise operator & is used to check whether a number is Odd or Even.

When the binary equivalent of a number and 1 is operated with Bitwise & operator, the result is either 0 or 1.

if the result is 0 then it is an Even number, otherwise, it is an Odd number. 

Sample output is shown below:

Enter a number: 6
The number 6 is even

Enter a number: 5
The number 5 is odd
