Hey,
I have noticed when you use srand or rand you write:
rand() % 99 + 1I was wondering about the 1, is it just tradition to use it or is it from 1-99?
Just because i was wondering how i could make it between say 20 and 40 etc

It's not, however, a question about srand. That merely 'seeds' rand. You want to get random numbers which is rand.

I skimmed the article, but is the only problem with rand() that RAND_MAX may not be one less than a multiple of your maximum? Like if you do rand()%3, and RAND_MAX+1 is a multiple of 3, will that be truly random?
