A quadratic equation is a second-degree polynomial equation in the form ax² + bx + c = 0, where a, b, and c are constants and a is not zero. Quadratic equations are common in mathematics, physics, and engineering, and solving them programmatically in C is a great way to practice conditional statements, math functions, […]

Compound interest is a common concept in finance where the interest earned is added back to the principal, and future interest is calculated on this new amount. Unlike simple interest, where interest is calculated only on the principal, compound interest grows faster and is used in savings accounts, loans, and investments. Writing a program to

Simple interest is a basic concept in finance and mathematics. In programming, calculating simple interest is a common exercise for beginners to practice arithmetic operations, variable usage, and input/output handling. A simple interest calculation helps you understand how to work with formulas and store results in variables in C. The formula for simple interest is:

Temperature conversion is a common task in programming and real-world applications. While converting Celsius to Fahrenheit is often taught first, converting Fahrenheit to Celsius is equally important. This program teaches you how to handle user input, perform arithmetic calculations, and display output using C. By writing a complete program for this conversion, you will understand

Temperature conversion is a common task in programming and real-life applications. Converting Celsius to Fahrenheit helps beginners understand how to work with variables, mathematical operations, and formatted output in C. In this tutorial, we will write a complete C program to convert a temperature entered in Celsius to Fahrenheit. We will explain each part of

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
