Understanding ASCII values is important for anyone learning C programming. Every character in C has a corresponding numeric code called the ASCII value. This code helps computers store and process text efficiently. In this tutorial, we will write a complete C program to find the ASCII value of a character entered by the user, explain […]

Generating a multiplication table is one of the first programs beginners learn in C. It helps you understand loops, input and output, and basic arithmetic operations. Writing a program to print a multiplication table also improves your understanding of how to structure code and manage repeated operations efficiently. In this tutorial, we will write a

An Armstrong number, also known as a narcissistic number, is a number that is equal to the sum of its own digits raised to the power of the number of digits. For example, 153 is an Armstrong number because $1^3 + 5^3 + 3^3 = 153$. Learning how to check for Armstrong numbers in C

Finding the sum of digits of a number is a common problem in programming. It teaches beginners how to work with numbers, loops, and arithmetic operations in C. For example, if the number is 1234, the sum of its digits is 1 + 2 + 3 + 4 = 10. Learning to calculate the sum

A palindrome number is a number that reads the same forward and backward. For example, 121, 1331, and 12321 are palindromes. Checking whether a number is a palindrome is a classic programming exercise that helps beginners understand loops, conditional statements, and number manipulation. In this tutorial, we will write a complete C program to check

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,
