Quick C++ Question

I was just wondering if it is possible to specify parameters for the rand() function, eg between 1 and 100.

Any ideas would be greatly appreciated
Thanks

#include <cstdlib>
#include <ctime>
#include <iostream>
using std::cout;
using std::endl;

int main()
{

    int j;
    const int N = 100;

    // Set evil seed (initial seed)
    srand( (unsigned)time( NULL ) );

    for (int i = 0; i < 5; i++) {
        j = (int) N * rand() / (RAND_MAX);
        cout << j << endl;
    }

    return 0;
}

This code should work, havent tried it but found it here

Or just use

rand() % max;

to get a number between 0 and max-1 inclusive.
