How can I define what should be the minimum value in a rand() and the maximum?
(e.g. I want to make a rand() from 85(including it) to 100(including it))

rand() will return an integer from 0 to 32767 depending on implementation, so you must work with that.

rand () % (100 - 85 + 1) + 85

Placing this in to a function is appropriate,

int myRand(int low, int high) {
   srand(time(NULL));
   return rand() % (high - low + 1) + low;
}

The % is the modulus operator to return a remainder, useful for limiting larger numbers.

This will essentially return a random number between 1 and 15, then add low again to make it between 85 and 100.
