I don't think this is supposed to happen.

When I use an INT program, something goes wrong.

Here's a little example:

int main()
{
cout<<"Stupid int main thingy!! I'm sick of it!!";
system("PAUSE");
return 0;
}

It runs fine the first time, but when I try again it says "implicit declaration of function `int system(...)'"

In order to get it going again, I have to start a new project.

Anybody know what's going on and how to fix it?

Thanks.

Include some headers.
Also, consider using namspace std.

Well, this works for me :

Code:

#include <stdlib.h>
#include <iostream.h>

int main()
{
    cout<<"Stupid int main thingy!! I'm sick of it!!";
    system("PAUSE");
    return 0;
}

*Borland C++ 5.02*

What compiler are you using?

Well like they said it all depends what compiler your using. Also with system("Pause") You have to use the <stdlib.h> header file. Some compilers need .h others dont. Some dont pick up std::. Tell us what compiler and we can help

My compiler. . .

I had thos things included, i just didn't show them when I posted.

Im using Dev c++ and dont have that problem. Works fine with me. are you still having problems?

When you wrote int main() did you write INT main() by mistake?
Because they are different.

Code:

#include <cstdlib>
#include <iostream>

int main()
{
    std::cout << "Stupid int main thingy!! I'm sick of it!!";
    std::system("pause");
}

C++ puts everything in namespace std (except macros of course).

Okay, I got it now. . . I had to include 'cstdlib'.

Thanks for the advice.

Code:

#include <cstdlib>
#include <iostream>

int main()
{
    std::cout << "Stupid int main thingy!! I'm sick of it!!";
    std::system("pause");
}

Where's the return value? Great thinking imov!

Hunter, you are about to be crapped on. (JK)

In C++, when you declare main to return int, the default return value is 0. Hence, by standard C++'s definition, return 0 isn't needed. But, some compilers might choke if you don't include it b/c not all compilers are completely standard.

Eww, where'd all this brown stinky stuff come from?

I think I better delete my post lol oh wait, what about those people whose compilers would choke? NO, I'd better leave it!
