Here is an example from PROGRAMMING WITH C++ by John Hubbard
(ISBN 0-07-114328-9), a very good text book on C++ to get you going.

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

main()
{
	unsigned seed = time(NULL);		// assigns the number of seconds

						// elapsed in 20th century to seed
	srand(seed);				// seed the randomiser
	for (int i = 0; i < 32; i++)
		cout << 1 + rand()%6 << " ";	// simulate dice - random number would
						// be from 0 to 5 hence the 1 +
	cout << endl;
}

Hope it helps
