Installation

To run the programs, you need a C compiler such as gcc.
On Linux/macOS, you can install GCC using:

sudo apt-get install build-essential   # Ubuntu/Debian
brew install gcc                       # macOS (Homebrew)

On Windows, you can use MinGW or an IDE like Code::Blocks or Dev-C++.

Usage

To compile and run a C program:

gcc filename.c -o program
./program

Example:

gcc basics/linked_list.c -o linked_list
./linked_list

Features

• Basics: Arrays, Fibonacci series, Linked List, Stack, Queue
• Searching Algorithms: Linear Search (sorted & unsorted), Binary Search
• Sorting Algorithms: Bubble Sort, Insertion Sort, Merge Sort
• Clear and simple C implementations

Examples

Compile and run a sorting algorithm:

gcc sorting_algorithms/merge_sort.c -o merge_sort
./merge_sort

Run a searching algorithm:

gcc searching_algorithms/Binary_Search.c -o binary_search
./binary_search
