Hello
I'm working on an application.
I need as big arrays as possible. At home I work with linux there I can declare array as big as this: char buffer[1000000]. No probleme.
In work I'm working with boreland C++ 4.5 (WinXp) and I can't declare biger size of array as buffer[20000].
It tels me << constant is long << and << array size too large;
It is possible to change this? or Is there some reason to not declare bigger Arrays like this?
Please help...

Depends on which version of that compiler is used -- 16-bit MS-DOS or 32-bit MS-Windows? 16-bit can create arrays up to only 64,000 bytes (large memory model), or 16,000 long integers. There is no work-around other than to redesign your program or use a modern 32-bit compiler, which is one reason MS-DOS is dead and buried.
Borland 4.5 is a 16 bit compiler. Upgrade to Borland 5.5 for 32 bit.

Why stick to Borland ???
If you are thinking about compiler migration better go for the free Visual Studio 2005 free edition or for GCC mingw compiler which nowadays most of the people use.

BTW since you seem to be a Borland proponent you might want to take a look here:

Nothing personal, just found these when i was once looking for good compilers.

Cant imagine why you want to allocate all that space statically. Use another data structure which resides on the heap - a list perhaps.

boaland 5.5 and earlier have the same problem as VC++ 6.0 -- they are too old and do not support current C++ standards very well. And that is a big problem for new people who are trying to learn modern c++ with an ancient compiler. There are a few legatimate reasons I can think of for using those old compilers (such as support of legacy programs) but most people should be using newer compilers. when you say "they work" do you mean they work with code written in 2006 or code written in the 1980s and 1990s (10 years is a lifetime in the software and compiler industries!) The last time c++ standards were upgraded was in 1999 which is well after those borland and microsoft vc++ 6.0 compilers were produced.

The Visual Studio 2005 free edition is huge! Kind of takes over your computer. I would go for GCC which is part of the free Dev-C++ IDE.
