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 GCD and LCM using recursion with the Euclidean algorithm. The GCD (Greatest Common Divisor) is the largest number that divides both inputs with no remainder. The LCM (Least Common Multiple) is the smallest number divisible by both. Once the GCD is known, the LCM follows from a simple identity: GCD(a, b) …
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 …
