Compile C++ Helloworld.cpp on VSCode and Mingw

Question

I am trying to compile and run a simple HelloWorld program via VSCode on Windows 10 but it fails to compile, even when following their tutorial .

The only feedback I receive is:

The terminal process "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command & 'C:\Program Files (x86)\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin\g++.exe' -g c:\Users\admin\programming\helloworld.cpp -o c:\Users\admin\programming\helloworld.exe" terminated with exit code: 1.

I don't even receive any further information what exactly has failed. How can this can be fixed? Quite curiously, the same command

& 'C:\Program Files (x86)\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin\g++.exe' -g c:\Users\admin\programming\helloworld.cpp -o c:\Users\admin\programming\helloworld.exe

performs perfectly well when I invoke it in a separate powershell.

C:\Users\admin\programming\Helloworld.cpp

#include <iostream>
#include <vector>
#include <string>

using namespace std;

int main()
{
    vector<string> msg {"Hello", "C++", "World", "from", "VS Code", "and the C++ extension!"};

    for (const string& word : msg)
    {
        cout << word << " ";
    }
    cout << endl;
}

Answer 1

Can you try returning zero in your program?

return 0;

Maybe the program is actually compiling and running but the non-zero return is interpreted as a failure.
