Write a C program to demonstrate the recursive function.Recursion is the programming technique that a process invoking itself again and again. In this program, We reverse the given number and checks it is a palindrome or not.

Exercise 4-13. Write a recursive version of the function reverse(s), which reverses the string s in place. An iterative reverse uses two indices walking inward from both ends, swapping until they meet. The recursive version does the same with the call stack: each call receives left and right indices, swaps those two characters, then recurses …
Exercise 4-12. Adapt the ideas of printd to write a recursive version of itoa; that is, convert an integer into a string by calling a recursive routine. K&R’s printd (Section 4.10) prints a number recursively: recurse on n/10 to print all leading digits first, then putchar(n%10 + ‘0’) on the way back up. itoa must …
This C program finds the GCD (Greatest Common Divisor) and LCM (Least Common Multiple) of two numbers using recursion. Recursion is a technique where a function calls itself to solve a smaller version of the same problem. The GCD is computed with the classic recursive Euclidean algorithm, and the LCM is then derived from it …
The Fibonacci series in C is a sequence where each number is the sum of the two preceding ones, starting from 0 and 1: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, … This page covers three approaches — iterative series printing, a recursive function, and a side-by-side comparison of their time and …
