Re: Compile time errors in C++ while generating random numbers

I checked my old Borland C++ compiler, you may have to add the .h to your includes!

#include<iostream.h>
#include<cstdlib.h>

Re: Compile time errors in C++ while generating random numbers

Can you please post your code here? That second part looks like you've not defined a function or something. Perhaps you've misnamed a function that you created, or you're #including a wrong library or something. Either way, post your code, and we'll be able to help you troubleshoot it.

Ahhh, all these clueless people.

Obviously iostream worked. But cstdlib didn't. Change it to stdlib.h instead. We won't even mention math.h

You might consider upgrading to at least Borland 5.5

Or one of these that have an IDE:
Code::Blocks
MSVC++ Express
Open Watcom C++/Fortran
Bloodshed DevC
