modulo?

Question

hey there.
i just learnt that with rand i am able to define a range of number (eg.1 to 20), my question is as i haven't seen any example in the lessons, how can i define a minimum value (eg.5 to 15)???

Answer 1

You need to figure out the math. There is no one single way to deal with range for RNG.

E.g. 5 to 15

std::cout << (5 + rand() % 11);

Now, if I want to generate random even numbers between 10 to 50? Random numbers which are multiples of 10 between 100 to 200?

Answer 2

thanks for the answer :).
