Question

I want to do that without using boost and “strange” things, I want to fill a board randomly for the game of life.

Answer 1

Just use stlib‘s rand():

#include <stdlib.h>
#include <time.h>

bool randomBool() {
  return rand() % 2 == 1;
}

int main ()
{
 /* initialize random seed: */
  srand ( time(NULL) );

/* fill up your game board here */

}

Just be aware that it will not yield perfectly uniform results. In order to achieve that, you’ll probably have to implement something yourself. For non-cryptographic purposes, you’re probably ok anyway.
