In this C Programming Language tutorial, we will show you how to compile and run a C program from the command prompt on a Windows computer. The video covers the entire process, starting from installing the necessary C toolset, including the compiler and other required programs, to writing and running your first C program.

We’ll begin by explaining how to check if the C toolset is already installed on your computer. You’ll learn how to use the command `gcc --version` in the terminal or command prompt to verify whether the GCC compiler is set up correctly. If the toolset is not installed, we’ll provide a link to a detailed tutorial on how to install it.

Once the C toolset is installed, we’ll dive into writing a simple C program using Notepad (though you can use any text editor of your choice). We’ll guide you step-by-step on how to save your source file with the proper `.c` extension and include the necessary header files, such as `stdio.h`. Then, we’ll show you how to write the `main` function and display a simple message like “Hello, World!” on the screen.

Next, we’ll demonstrate how to compile your C source file using the GCC compiler. You’ll learn how to create an executable file and run it from the command prompt. We’ll also show you how to provide a custom name for the executable file by using the `-o` flag when compiling.

In addition to basic compilation, we’ll explain how to use various flags to customize the compilation process. For instance, we’ll teach you how to enable warnings with the `-Wall` flag and how to specify a particular C standard if necessary. We will also discuss how to handle warnings during compilation, including examples of unused variables and how the compiler displays those warnings.

Finally, we’ll walk through the process of running your executable and troubleshooting common issues you may encounter, such as warnings or errors in your code. You’ll learn how to address them, ensuring your C program compiles and runs successfully.

By the end of this tutorial, you'll be confident in compiling and running C programs from the command prompt in Windows. Whether you are a beginner or just need a refresher, this video covers all the essential steps and tips for working with C programs on Windows.
