i need to to know how to use srand and time together thank you

[Disch]

1) call srand once and only once when your program starts

2) call rand as many times as needed after that. Each call gives a different random number.

int main()
{
  // seed it once:
  srand(time(0));

  // a bunch of random numbers:
  for(int i = 0; i < 10; ++i)
    cout << rand() << endl;
}
