C Program to find Number Even or Odd using Bitwise AND ( & ) Operator

c program to understand the usage of Bitwise Operator & .

                   (Or)

Example c program for Bitwise operator & ..

PROGRAM :

#include<stdio.h>
#include<conio.h>
main()
{
    int n,i;

    printf("\n Enter a Integer Number to find Even or Odd:");
    scanf("%d",&n);
    i=!(n&1);  /* & is a bitwise and operator*/
    if ((i))
        printf("\n The Entered Number Is Even");
    else
       printf("\n The Entered Number is Odd");

    getch();
    return(0);
}

Sample Output: (using GNU GCC Compiler with Code Blocks IDE)
  1) Enter a Integer Number to find Even or Odd: 5
     The Entered Number is Odd
  2) Enter a Integer Number to find Even or Odd:
     The Entered Number Is Even
  

      n       1     (n&1)     !(n&1)

    

n=2  0010   0001    0000      returns 1 ( if statment executes)    

n=3  0011   0001    0001      returns 0 ( else statment executes)
