Installed VS code, there is no builder to build my code, even though I installed MinGW-w64

Question

I have very recently installed VS code and am an absolute newbie. I first had a different problem because I installed the wrong type of MinGW-W64, which I have now uninstalled, then it seemed to fix the problem, until I tried to build the code. A photo of what going to terminal > run build task shows me is shown in this photo. Terminal>Run Build Task

Extra details: I am using 3 c++ addons, C/C++ version 1.4.0, C/C++ Extension Pack version 1.0.0 and C++ Intellisense version 0.2.2. My code is an extremely simple and correct:

#include <iostream>

using namespace std;

int main()
{
    cout << "Hello World" << endl;
}

My goal: I'm hoping to be able to run this code as intended in https://code.visualstudio.com/docs/languages/cpp (the tutorial I followed)

Answer 1

By looking at the error message, you are currently executing the program in C:\Users\{username} directory however your source code file helloworld.cpp is present in C:\Users\{username}\OneDrive\Desktop folder.

use cd "C:\Users\{username}\OneDrive\Desktop" in your terminal to navigate to the folder and then run the g++ helloworld.cpp -o helloworld command. After that run .\helloworld to run your program.

Note that if you using VS code to build your program as mentioned here, then you only have to execute the .\helloworld command to run it.
