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...
