problems compiling

[batteryphil]

I have bought c++ for dummies and downloaded dev c++. The problem is I can't get it to compile. I am new so don't be to hard on me. Is there a setting I may have wrong or is it vista? I have tried other compilers and none of them will compile. Please help.

could you post your code and the error it gave you.

[batteryphil]

The code is just the maine. In the book it says it will open a console window and say "press any key to continue".
#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
system("PAUSE");
return EXIT_SUCCESS;
}
But instead it gives this error
Compiler: Default compiler

Did I miss something I was supposed to do? I have no idea what any of that means yet?

It runs fine when compile it. When I ran it. When you downloaded dev-c++ did you get it with or without mingw. Also try this code it will do the same thing as yours with a few things taken out.

Code: Select all

#include <iostream>

int main()
{
system("PAUSE");
return 0;
}

you do not need using namespace std unless you are working in the standard namespace i.e. cout, cin, cerr etc.

I tried what you posted and it didnt work either. It must be the mingw. What is that and how do I get it into dev c++.

[herby490]

Dev-C++ is an IDE(Integrated Developers Environment). An IDE is basically point and click and press a button to compiler(assuming you have an compiler to go with it). If you don't have a compiler to go with it an IDE is essentially notepad with a few extra features. Mingw on the other hand is a compiler that unless you have a IDE to go with it has to be run from the command line. So if you got Dev-C++ by itself then you will not be able to compile any code. For the day or two that I used Dev-C++ I know that it runs fine on vista(and windows 7 if it matters). I hope my explanation is ok. I am sure there is a better way to explain it.

Could download Code::Blocks :P There's a win32 installer that includes MinGW.
http://downloads.sourceforge.net/codebl ... -setup.exe

Haven't used Dev-C++ in ages so as far as setting up the compiler I really don't remember.

Yeah I would use Code::Blocks or Visual C++. Dev-C++ is kinda old.

I'm downloading codeblocks now. Thanks for the advice guys! I'll let you know if this solves the problem.

[batteryphil]

Works Great guys! Thanks a lot.

I am glad it works for you.
