what language?

in C you create an array and then fill it with your random numbers, like

Code:

#include <stdlib.h>

int main() {
  int ra[10];
  int i;
  for(i=0;i<10;i++) {
    ra[i] = rand();
  }
}

man rand for details.

then you've gotta scale the numbers down.

change the

Code:

    ra[i] = rand();

to

Code:

    ra[i] = rand() % 10;
