how to make a exe file which can run directly

I am using Microsoft Visual C++ to write a C program. But when compile it, it create a exe file. When I double click on it, it open and close immediately. Yes, it run fine in the cmd window.

The question is, how can I make an exe file which can run when I double click on it. ( what I was trying to say is, when I download an exe from the internet, I often double click on it and it run, no install require). I want to create an exe like that.

Could you please guide me on how to do it?

Thank you very much

You could add the following to the end of your program's main function ( but before the return satement:

Code:

---

int main()
{
    //...other code...
    getchar();
    return 0;
}

---

This makes the program wait for input at the command line, to end your program you could just type in a character and press the enter button on your keyboard.

Also, Visual C++ has an option to run it as well that doesn't require the getchar(); line. If you navigate to Debug -> Start Without Debugging that should run your program without closing immediately.

I understood what you meant. But I guess I didn't make my point clear enough.

My point is to make an exe program which is no longer a DOS or cmd program. I want to make a window program.

Right now, I just want to make a very simple window environment exe program. Such as enter an input and print that input out.

I know how to write the code, but I don't know how to make a window environment exe.

Could you please help me to do so?

Thanks

So, you want to use a GUI(Graphical User Interface). For that, you need to start reading some tutorials on GUI programming, which will differ depending on your OS platform. If you are using Windows, it's the win32 library, in Linux the X window system or others(depending on the flavor).

Thank you very much. I'll look into it

When I make Windows equivalents of my programs, I always append the following.

Code:

---

#include <conio.h>

main() {
    /* code code code... */
    getch();
}

---

This will leave the CMD window open until the user presses a key.

getch is non-standard and main must return int.
You may as well use getchar. But this is only necessary for console programs.
