Getting into C++ Downloading gcc.

Getting into C++ Downloading gcc.

[Ray McAllister]

Hi, I'm totally blind. I do most of my programming in BASIC, but I use C++
now and then, actually, for drawing fractals.  I code graphics.  I've been
using Dev-C++ because it's the only thing I can find compatible with my
screen reader.  I don't like how I can't set up a char array bigger than
1400 by 1400  as I might want to make a fractal bigger than that.  I have
the computer fill an array with the fractal data for colors, and then it
writes a bitmap file with the data and I can access that through BASIC or
just show it to a friend.  All Dev-C lets me do for array size is 1400 by
1400 in an array, and that's using chars.  I'd use Booleans, but I need to
include color data for each pixel.  I wonder if GCC would be better with
that.  I also need to knowk, please, how and where to download GCC, the
latest version.  I'm not finding info on that.  In addition, when I run the
dev-c++ programs from bASIC, a window comes up on the screen saying so. Is
there a way, in GCC, to prevent that? 

 

Thanks, 

Ray McAllister.

You should be able to create arrays bigger than that, limited only by
the memory available on your computer.

You might not be able to create such large arrays on the stack, or as
a global variable, but you could create it on the heap:

char* array = new char[10000*10000];

Or a better way to do that might be:

#include <array>
#include <memory>
using array_type = std::array<char, 10000*10000>;
auto array = std::make_unique<array_type>();

Dev-C++ is not a compiler, it's just an IDE, and it uses the Mingw
port of GCC for the compiler. That means you're already using GCC.

As explained at https://gcc.gnu.org/install/binaries.html the GCC
project does not provide binaries to download, we only provide source
code. There are third-party binaries available, and the mingw and
mingw-w64 ports of GCC for MS Windows are available from their
respective projects. The https://gcc.gnu.org/install/binaries.html
page has links to them, and there are other builds of them available
like http://tdm-gcc.tdragon.net/

I have no idea, that sounds like a Windows feature, not something
caused by the compiler. Maybe somebody else can help there.
