Reversing a number is a fundamental exercise in C programming. It helps beginners understand loops, arithmetic operations, and how numbers can be manipulated at the digit level. In this tutorial, we will write a complete C program to reverse a number using both iterative and recursive methods. Each line will be explained carefully, and common […]

Finding the Least Common Multiple, or LCM, of two numbers is a common task in mathematics and programming. The LCM of two integers is the smallest positive integer that is divisible by both numbers. Understanding how to calculate the LCM in C helps beginners learn about loops, conditions, and arithmetic operations. In this tutorial, we

The Greatest Common Divisor (GCD) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. Finding the GCD is a fundamental concept in mathematics and programming, often used in simplifying fractions, solving problems involving ratios, and algorithms in computer science. In C programming, calculating the GCD introduces beginners to

Finding prime numbers within a given range is a common exercise in C programming. A prime number is a number greater than 1 that is divisible only by 1 and itself. Numbers like 2, 3, 5, 7, 11, and 13 are prime, while numbers such as 4, 6, 8, 9, and 12 are not. Printing

Learning how to check if a number is prime is one of the most common exercises for C programming beginners. A prime number is a number that is greater than 1 and divisible only by 1 and itself. For example, 2, 3, 5, 7, 11, and 13 are all prime numbers, while 4, 6, 8,

The Fibonacci series is one of the most famous sequences in mathematics and computer science. Each number in the sequence is the sum of the two numbers before it. The series begins with 0 and 1, and from there, every next number is formed by adding the previous two. So, the sequence starts as 0,

Calculating the factorial of a number is one of the most popular exercises for beginners learning C programming. The factorial of a number is defined as the product of all positive integers from 1 up to that number. For example, the factorial of 5, written as 5!, is equal to 5 × 4 × 3

Calculating the sum of natural numbers is a very common beginner exercise in C programming. Natural numbers are the positive integers starting from 1, 2, 3, and so on. Finding their sum helps learners understand loops, mathematical formulas, and how logic is translated into code. This program may look simple at first glance, but it

Finding the largest of three numbers is a fundamental exercise in C programming. This program helps beginners learn how to use conditional statements effectively and understand the flow of decision-making in code. Learning this concept is crucial because it lays the foundation for more advanced programs, such as comparing values in arrays or determining the

Finding the largest of two numbers is one of the basic exercises in C programming. This simple task helps beginners understand how to compare values using conditional statements and teaches the logic behind decision-making in programming. Learning this concept is essential because it forms the foundation for more complex comparisons in future programs, such as
