Hi ppl,

I am coding a program and in that i have to handle a very large amount of data. It can vary from 1 to 1000000000. I am using "C" and "unsigned long int" data type, but my program hangs every time i try to run it over 1000000. Any suggestions??? Posted in: #Coffee Room

Why don't you try C#.NET 2008 and use BLOB format?

I said C# because, it is kind of Platform Independent. Mono for Linux and Mac... 馃榾 And you can use your own C / C++ Codes to work on it... 馃榾 And, BTW, what is the logic you are trying to implement? I mean, I didn't understand your problem... 馃様

Basically i have been given a task to find out primes in the range of 1 to 1000000000. So i made the code but my program hangs as soon as i input data greater than 1000000. So i thought may be its the problem with data type.

Yeah, first of all data type should be some kinda looong integer... and secondly, C doesn't have that much memory to handle the data... 馃様

Yeah.....its looks like that. And can you please elaborate the part with memory. Whats this memory restriction???

Dude, C Applications are 16 bit apps, which cannot handle more than 16bit of instruction and data... Whereas C# is a 32 bit application and it can handle much higher data... 馃榾 Got it?

Well, you can pretty much do the same function on C just with a different approach. If you machine has multiple cores, you can program in threads so that you make them run on different processing units concurrently. I think that would be enough to handle the amount of data you are going to feed it.

In case that would not be enough, C# would be there to do it for you.

Actually, that doesn't work in C. Since, DOS works only in a single thread model, C too does the same! 馃様
