Issues Compiling on Windows 10

Hi,

This is my first post!

I mainly program in Python, with a bit of Visual Basic. I've recently taken an interest in C++.

I'm having an issue compiling even the most basic program on my system. I've tried using MinGW and Visual C++ compilers, but the same issue arises.

Trying to compile this, the most basic program, all I get is a blank Command Prompt window with a flashing cursor.

Code:

---

#include <iostream>

using namespace std;

void main()
{
    cout << "Hello, World!" << endl;
    cin.get();
}

---

The line "Hello, World!" doesn't print and the program seems to hang. When I try to re-run I get a Permission Denied error.Closing the Command Prompt window leaves the process running in memory.

It doesn't show in Task Manager, but when I run Tasklist
from Command Prompt I see the process, which I need to kill using

Code:

---

Taskkill /PID {id-no} /F.

---

As I said, I've tried using other compilers. I've also tried changing the write permissions in the directory the application is running from. I've even excluded the directory from my AntiVirus as I've read this can be an issue.

So. I'm stuck with this seemingly simple issue, with the solution probably staring me in the face, but I can't seem to see the wood for the trees.

Maybe an outside perspective will reveal a solution?

What about the permissions of the executable file itself?

Tried that too. Using the VS2015 C++ compiler I can see the compilation seems to have been successful; there are no errors returned, and both the object file and the executable are there.

If I navigate to the directory using Explorer and try to execute the .exe file Explorer hangs and I have to restart.

It's possible that your antivirus software is blocking it. Some watch for any .exe file to change, and block access.

It's generally a terrible idea, but have you tried running the shell in Admin mode to see if it runs fine then? Because if that doesn't work, then maybe the error message hides another problem.

Edit: e.g. such as what Elkvis suggests.

So simple, yet so elusive!

I think that's exactly what's happening. Even though I'd added an exclusion to the directory it was still blocking the .exe. I had to explicitly uncheck the scanning of .exe files when opening in the AV software.

Not sure how safe that is, but the code runs!

Thanks guys!

Appreciate the help.

Glad I could help.

Btw, main should return int, not void.
