User defined seed value

I'm doing a homework assignment that asks the user to enter a positive interger seed value to be used for generating a random number to be used in a two player game of rolling dice. My question is how do I go about using that entered value directly in the random number generation? I looked through the threads and FAQ already and I could not find a definite answer.

PHP Code:

---

                printf("Enter a positive integer seed value: ");
    scanf("%i",&seed);
    printf("Enter number of rolls of dice: ");
    scanf("%i",&num);

    ?die = 1 + ( srand(seed) % 6 );?

srand is how you "us[e] that entered value directly in the random number generation". You do srand once (once only, mind), which sets the seed for future calls of rand.

so...

PHP Code:

---

srand(seed)
die = 1 + (rand(seed) %6 );

is that correct?

or would it be

PHP Code:

---

srand(seed)
die = 1 + (rand() % 6 );

rand doesn't take any arguments.
