If you’ve just started learning about recursion in your programming course, it might feel a little confusing at first. But don’t worry — in this guide, we’ll break it down into small, easy-to-digest pieces with sample C codes and clear explanations. By the end, you’ll understand   what recursion is ,   how it works , and   when to use it . Tip:  You can try out all the code examples in this article using an online compiler like  Programiz Online C Compiler . No installation needed! What is Recursion? Recursion  is a programming technique where a function  calls itself  to solve smaller parts of a problem until it reaches a simple case (called the  base case ). Think of recursion like solving a puzzle where each piece depends on solving a smaller puzzle first. Key Concepts Recursive function  — a function that calls itself. Base case  — the condition that stops the recursion. Recursive case  — the part of the function where it c...
