In this tutorial, we’ll guide you through the steps to compile and run a simple C++ program directly from the command prompt on your Windows computer.

Before we dive in, make sure to download and install the C++ toolset, which includes the compiler, debugger, and other necessary tools. If you’re unsure how to install it, check out the tutorial youtu.be/sQjI5vqKUEo for detailed instructions.

Once the toolset is installed, we’ll create a basic "Hello, World!" C++ program using Notepad, save it with the .cpp extension, and compile it using the g++ compiler. You’ll also learn how to handle common C++ flags like -Wall and how to customize your executable file name.

Here’s what you’ll learn in this video:
How to write a basic C++ program.
How to compile the C++ program from the command prompt using the g++ compiler.
How to run the executable and display the program's output.
How to use compiler flags and set custom executable names.
