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:
```
sudo apt install clang
```
- Windows: Please follow these instruction from Using GCC with MinGW.

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!
```
