Hexadecimal numbers are base-16 numbers represented using digits 0–9 and letters A–F. Converting from decimal to hexadecimal is a common task in programming, particularly in memory addressing, graphics (like color codes), and low-level development. This section explains how to write a C program to perform the conversion. Understanding The Problem Decimal numbers use base-10, while […]

Octal is a base-8 number system that uses digits 0–7. Decimal, on the other hand, is the familiar base-10 system we use daily. Converting octal numbers into decimal is essential in programming when working with legacy systems, number systems, or input/output representations. In this article, we will write a C program to convert an octal

Decimal is the base-10 number system we use in everyday life, while octal is a base-8 number system that uses digits from 0 to 7. Octal numbers are often used in programming and computer systems, particularly in older systems and in Unix file permissions. In this article, we will write a program in C to

Decimal numbers are the standard number system we use daily, based on base 10. Computers, however, work with binary (base 2) numbers. Converting decimal numbers into binary is a fundamental operation in programming, helping us understand how values are stored and processed internally. In this article, we will write C programs to convert decimal numbers

Binary numbers are the foundation of digital systems, where data is represented using only two digits: 0 and 1. Decimal numbers, on the other hand, are the numbers we use in everyday life. Converting binary to decimal is essential for understanding how computers interpret and display data. In this article, we will write a program

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
