C Program to Demonstrate the increment and decrement operators

C program which demonstrates the working of increment(++) and decrement(–) operators. Increment operator ++ adds 1 to its operand and Decrement operator — subtracts 1 from its operand. These operators may be used either as a prefix operator or post-fix operator.

C Program to find GCD and LCM using Recursion

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 …

Fibonacci Series in C – Iterative, Recursive, and Array Methods

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 …

Factorial Program in C – Iterative and Recursive with Output

The factorial program in C is one of the most common exercises for learning recursion and loops. The factorial of a non-negative integer n, written n!, is the product of all positive integers from 1 to n. By definition, 0! = 1. This page covers two approaches — iterative and recursive — with compile-verified code, …

Array search program in C

Very often we encounter a situation where we have to search for a given target value in a list of values. Simple value types like integers are stored in arrays. This program demonstrates how to do a search within an array by using a method called linear search. Linear search, also called as ‘Sequential search’ …

C Program to demonstrate the ‘getchar’ function.

The getchar() function reads a single character from standard input (the keyboard) and returns it. It is one of the simplest input functions in C and a great way to understand how the input buffer works. In this program we use getchar() in a loop to read text entered by the user and count how …
