First, make sure you include a couple of things: #include <cstdlib> // this is for rand() and srand() #include <ctime> // this is for time() Then, in main you will need to set the seed for the rand function before calling rand(); int main() { srand(time(NULL)); int rand0to9 = rand() % 10; // here I've called it to give me a random int 0 to 9 return 0; }
