[gameprogrammer] Re: Making random numbers in C++

srand(int) won't generate you random nubner it will only start the
generator ....

Generating random number in stdlib is implemented like:

global int x

void srand(int start_value) {
  x = start_value
}

int rand(void) { // that what you need
   x = some_function(x)
   return x
}
