Run C++ in VSCode

This guide will walk you through the steps to compile and run a C++ program in Visual Studio Code (VSCode) using the clang++ compiler.

Prerequisites

Before you begin, ensure that you have the following:

• Visual Studio Code installed. You can download it from here.
• clang++ installed on your system.
  • macOS: clang++ is pre-installed with Xcode Command Line Tools. Install it with:

    xcode-select --install

  • Linux: Install clang++ using the package manager:

Steps to Compile and Run C++ Code

1. Open the Integrated Terminal

• In VSCode, open the Integrated Terminal by navigating to:
  • View > Terminal
  • Or press Ctrl + J (or Cmd + J on macOS) to open the terminal.

2. Compile the C++ Program with clang++

• In the terminal, run the following command to compile your main.cpp file using clang++:

  clang++ -o main main.cpp

• This will generate an executable file named main.

3. Run the Executable

• After building the program, you can run it directly from the terminal by typing:

  ./main

• You should see the following output:

  Hello, World!
