This repository contains a collection of C programs that illustrate various concepts in C programming. The programs are organized by topic and are accompanied by brief comments explaining the key concepts and techniques used.
To compile and run these programs, you will need a C compiler such as GCC or Clang. You can install these compilers on your system using a package manager or by downloading them from their respective websites. Once you have a compiler installed, you can navigate to the directory containing the program you wish to run and use the gcc or clang command to compile it, like so:
$ gcc program.c -o program
