Compiling and Debugging with Multiple Files

Please read before you start

Changing your tasks.json

If your project has multiple files, you can configure the `tasks.json`file to compile all of the C++ files you currently have open. Do this
by opening .vscode -> tasks.json and replacing `${file}` with all of the .cpp files in your folder under the `args` entry.

For example, if you have a file named `main.cpp` and another file named `functions.cpp`, you would replace `${file}` with `main.cpp', 'functions.cpp`,

With this configuration change made, go back to the file with the main
function. You should be able to run the compiler normally as you have done before.

This is the example for a Hello world program
