Toggling a bit means changing its state: a 0 becomes 1, and a 1 becomes 0. This operation is widely used in low-level programming, embedded systems, and digital logic applications. In this article, we will learn how to toggle all bits of an integer using C programming. Understanding The Problem An integer in C is […]

Set bits are the 1s present in the binary representation of a number. Counting set bits is a common problem in computer science, especially in fields such as cryptography, error detection, and low-level programming. In this article, we will explore three approaches: simple bitwise shifting, Brian Kernighan’s algorithm, and the built-in GCC function. Understanding The

A rhombus number pattern is a symmetric arrangement of numbers shaped like a slanted rectangle. These patterns are excellent exercises for understanding nested loops and spacing in C. There are many variations, but in this article, we will explore four: a rhombus with increasing numbers, a rhombus with decreasing numbers, a hollow rhombus with increasing

An hourglass pattern is a symmetrical star pattern shaped like an hourglass, where stars form a wide top, narrow middle, and wide bottom. Printing this pattern helps beginners understand nested loops, conditional printing, and alignment in C. Understanding The Problem The program should take the number of rows for the top half of the hourglass

A butterfly pattern is a symmetrical star pattern shaped like butterfly wings. The pattern consists of two mirrored triangles, with stars expanding outward and then contracting, creating the appearance of wings. This exercise helps learners practice nested loops and spacing in C. Understanding The Problem The program should take the number of rows (for half

A right-angled triangle pattern is a simple triangular arrangement where the right angle is typically at the bottom-left. Printing such patterns helps beginners practice nested loops and alignment in C. Understanding The Problem The program should take the number of rows as input and print a right-angled triangle of stars. Each row contains an increasing

A hollow triangle of stars is a triangular pattern where only the borders of the triangle are printed, leaving the inside empty. This pattern helps learners understand nested loops, conditional statements, and proper alignment in C. Understanding The Problem The program should take the number of rows as input and print a triangle where only

A hollow square of stars is a square pattern where only the borders are printed with stars, leaving the inner part empty. Printing such patterns helps beginners understand nested loops and conditional statements in C. Understanding The Problem The program should take the number of rows (or columns) as input and print a square of

Pascal’s Triangle is a triangular array of numbers where each number is the sum of the two numbers directly above it. It has applications in combinatorics, algebra, and probability. This program demonstrates how to print Pascal’s Triangle using nested loops and combinatorial calculations in C. Understanding The Problem The program should take the number of

A hollow pyramid is a star pyramid where only the borders of the pyramid are printed, leaving the inside empty. This pattern is commonly used to practice nested loops, conditional statements, and alignment in C programming. Understanding The Problem The program should take the number of rows as input and print a pyramid where only
