A program to explain bitwise operators

#include <stdio.h>
 
void main()
{
    int a, b, c;
 
    printf("Enter a,b values: ");
    scanf("%d %d", &a, &b);
 
    c = a & b;
    printf("Bitwise AND result is\t %d\n", c);
 
    c = a | b;
    printf("Bitwise OR result is\t %d\n", c);
 
    c = a ^ b;
    printf("Bitwise ex-OR result is\t %d\n", c);
 
    c = a << 2;
    printf("Shift left result is\t %d\n", c);
 
    c = a >> 2;
    printf("Shift right result is\t %d\n", c);
 
    c = ~a;
    printf("Negation result is\t %d\n", c);
 
    printf("\n");
}
