Alright, I'm trying to learn C++ currently; but my compiler, Dev-C++ doesnt seem to wanna run any program I compile. So, how do i know if my program works if it wont compile?!

You've probably screwed up the compiler installation - I did the same thing the first time I used Dev-C++. What you have to realise is Dev-C++ is just an IDE the actually compiler is MinGW so make sure you have MinGW fully installed and setup correctly.

It could be that nothing is stopping it from closing
like if your code is
int main(whatever)
{
  cout<< "sometihng \n";
}

and you choose to compile and run in Dev, the program will just run and close.
Not sure if that's your problem but its possible

I think this is more of a compiler issue.  If it was the code, then the console would appear for less than a second before closing.

Completely free, and better than DevC++.. at least, I think so ;-). MingW is also pretty slow... There is a guide on the microsoft website for using the platform SDK with Visual C++ 2005.. The platform SDK gives you the files you need to build Win32 applications... The regular download MIGHT already have the stdlib (for using cout), but I'm not sure.

MinGW needs environment variables set to work, just google 'MinGW environment variables'.

Servu, go to the project's directory, go to /bin/Debug/ and see if there's an executable file there. If so, run it and see what happens (not the vshost)

There's such a double standard about religion in the modern world. Catholics can gather, wear white robes, and say "In nomine Patris, et Filii, et Spiritus Sancti" and be considered normal.

But if my friends and I gather, wear black robes, and say  "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn", we're considered cultists.

He's using Dev-C++ not VS.

I was talking about with VC++, find out if it's a problem on the compiler side, computer side, or if it's something similar to what Soulrivers said, because that's happened every now and then with me, where the console comes up and leaves so fast you dont see it at all

..All i did when i first started was installed the DevC++ download that comes complete with MingW, and sets it up for you...Or it did back then at least.
.Though these days i use Code::Blocks with MingW

AcidGame posted VC++; He downloaded and tried it and it didn't work either.
Theres probably some sort of mix up here though; why not there always is.
