Re: srand trouble 16 Years Ago by Narue >I think it is something to do with srand( time(NULL); Nope, your logic is just wrong if you want game to end at exactly 1001. Notice how you don't check that condition every time game is incremented. You only check the condition after the inner loop has terminated. game could be incremented several times in the inner loop.

Srand question 17 Years Ago by Black Magic Hey, I have noticed when you use srand or rand you write: [CODE=C++]rand() % 99 + 1[/CODE] I 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 Re: Srand question 17 Years Ago by twomers A solution to what you desire is given pretty much straight away, but it makes an interesting read -- [url]http://www.eternallyconfuzzled.com/arts/jsw_art_rand.aspx[/url] It's not, however, a question about srand. That merely 'seeds' rand. You want to get random numbers which is rand. Re: srand function 14 Years Ago by mayur.sarode thanks..the srand seeding concept works!
