Hi all,

I'm doing some homework and am kind of stuck here. I'm doing a program that
needs two random numbers to be multiplied. Here is my code so far:

#include <iostream>
#include <cstdlib>

using namespace::std;

int main()
{
        int x = ( 1 + rand() % 9 );
        int y = ( 1 + rand() % 9 );
        int ans = 0;

        cout << "How much is " << x << " times " << y << "?" << endl;

return 0;

}

As I understand it the ( 1 + rand() % 9 ) should return a random number
between 1 and 9. Is this correct? I seem to be getting the same set of
numbers each time it is run. Can you tell I'm a newb? <g>

Thanks for any help.
