XOR Question

I was reading a thread about XOR, and having to do this for my current program had a question on it.

I know && and || are part of C,

so isnt there a way to have an XOR without doing several basic operations?(Like a command I havent yet seen)

Sure, the ^ operator performs an XOR and ^= does an XOR then assignment :-)

Code:

---

/*
How to set an int to 0 without saying
  var = 0;
*/
#include <stdio.h>
#include <stdlib.h>

int main(void)
{
  int a = rand();

  printf("%d\n", a);
  a ^= a;
  printf("%d\n", a);

  return 0;
}

the != operator.

All that xor does is return true if either operand is true, but not both. That's exactly what != does (considering you are dealing with just a single value representing true and a single value representing false ).

If you want the bitwise version of xor it actually has its own operator which is ^
