C Problem Solutions

Welcome to my collection of problem-solving solutions written in C programming language!
This repository showcases my journey in practicing and mastering C through various challenges and exercises.

What's Inside

  • Each file contains a standalone solution.
  • Organized by topics like conditions, functions, arrays, strings, etc.
  • Well-commented code for better understanding.

Topics Covered

  • Basic Input/Output
  • Control Structures (if, switch, loops)
  • Functions and Recursion
  • Arrays and Strings
  • Pointers and Dynamic Memory
  • File System and others

Getting Started

  1. Clone this repository:

  2. Compile any C file using GCC or your preferred compiler:

     gcc filename.c -o filename
 ./filename
