Hi, sorry for posting an [OT], but usually people on this list know everything :-) Since I don't know too much about programming I am frequently fascinated by simple things like Eratosthenes' sieve. As you might remember, one has to create a boolean array for that. The longer the array the more primes can be found. With malloc() I can create an array of length 100000000 (10^8) and the first 5761455 primes are calculated in a few seconds. So of course I would like to test length 10^9 but here my program crashes. So my questions: - is there some way to create a longer array? - or what are the alternatives? - do you know some kind of fine manual about this? Regards and thanks for all answers, Uli. ********************************************* * Peter Ulrich Kruppa - Wuppertal - Germany * *********************************************
