If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:

/*
 * Exclusive Disjunction
 */
#include <stdio.h>
 
int main()
{
    int p;
    int q;
    int r;
 
    printf("Enter a 1 or a 0 to xor:\n");
    scanf("%d", &p);
 
    printf("Enter a second 1 or 0:\n");
    scanf("%d", &q);
 
    r=p^q;
 
    printf("The xor of the values you've entered is: %d",r);
 
 
 
 
    return(0);
}
