Thread: Random Number

How can I make a function, or if there is already a function that will return a different random number each time I use it.

Like rand(1,10); will return a random number 1-10.

And if I start up the program again, or use the function again it won't return the same number.

Check the FAQ all the way down at the bottom under the heading Prelude's corner.

Code:

#include <stdlib.h>
#include <time.h>

int randnum (int start, int end)
{
    static bool notseeded = true;

    if (notseeded) {
        srand(time(0));
        notseeded = false;
    }

    return rand()%(end-start+1) + start;
}
