🚀 Getting Started

Prerequisites

To compile and run any of the programs in this repository, ensure you have the following installed:

• GCC compiler (verify with gcc --version)
• Git (for version control)
• Any C IDE or text editor (e.g., VS Code, Sublime Text)

Installation & Usage

1. Clone the repository:

   git clone [https://github.com/](https://github.com/)<your-username>/c-programming.git
   cd c-programming

2. Compile and run a program: Navigate to the desired directory (e.g., cd basics/) and execute the following commands:

   # Compile the source file (e.g., 'filename.c')
   gcc filename.c -o output
   
   # Run the compiled executable
   ./output
