/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

4. Install CMake via Homebrew
   • Install Cmake(for building C/C++ projects) using Homebrew:
   • Type cmake --version to check whether it's installed.

   • Add your source files and CMakeLists.txt
     1. Open the command palette by pressing cmd+shift+p
     2. Find the CMake: Quick Start
     3. Enter the name of the project
     4. Choose c++ project option
     5. Choose c++ executableoption
     6. Not Mandatory : include other extension package
     7. Choose the .cppfiles

8. Build and Run the program by selecting play button down the VSCode.

9. Configure Debugging
   • To debug the C++ program using LLDB, set up the launch.json configuration. Open your launch.json file and add the following configuration for debugging:
   • Read this in VScode_web

{
    "configurations": [
        {
            "name": "C/C++: clang++ build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "lldb",
            "preLaunchTask": "C/C++: clang++ build active file"
        },
        {
            "name": "C/C++: clang build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "lldb",
            "preLaunchTask": "C/C++: clang build active file"
        }
    ],
    "version": "2.0.0"
}

10. Final step is to choose a kits which a toolchain for compiling and linking the project.
    • Choose the kit in No Kit Selected section.
    • Or goes to the command palette, and select toolkit from CMake: Select a kit option.
    • Select the appropriate one and Happy Coding.
