This should demonstrate whats going on.
srand seeds the random number generator (makes numbers random)

% 10 means mod 10.
it will make it so
rand() %10 will output numbers between 0-9

code:
#include <iostream.h>
#include <stdlib.h>
#include <time.h>


int main() {
  srand(time(0));
  for (int p=0;p<30;p++) {
    cout << rand() % 10 << " ";
  }
  return 1;

}
