How to use the rand function to make numbers in a specific range?

Question

I would like to make random numbers in a specific range, like \"pick a random number between 18 and 35\"? How can I do that with the rand() function?

Answer 1

assume rand() give you a number between 0 and 1.0

then use rand() * (35 - 18) + 18 to get a random number between 18 and 35.

Edit: you don't need mod for this.
