Workspace

Create a .vscode folder in the workspace with:

• tasks.json - compiler build settings
• launch.json - debugger settings
• c_cpp_properties.json - compiler path and IntelliSense settings

Compiler build settings in .vscode/tasks.json

tasks.json for both LLVM and GCC:

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",

                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {

Debugger Settings in launch.json

.vscode/launch.json with input redirect - note difference beween the way it is configured on MacOS and Linux:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.

            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
