C Programming Calculator
C programming is a powerful and versatile language, widely used in system programming, embedded systems, and more. Calculations in C are fundamental to many applications, and mastering them is crucial for any C programmer.
- Enter the first number in the ‘Enter first number’ field.
- Select the operation you want to perform from the dropdown menu.
- Enter the second number in the ‘Enter second number’ field.
- Click the ‘Calculate’ button to see the result.
The calculator performs the selected operation on the two input numbers and displays the result. The formula used depends on the selected operation:
- Addition:
num1 + num2 - Subtraction:
num1 - num2 - Multiplication:
num1 * num2 - Division:
num1 / num2
Real-World Examples
Let’s consider three scenarios where C programming calculations are used:
- Temperature Conversion: Convert Fahrenheit to Celsius. Formula:
(F - 32) * 5 / 9 - Distance Calculation: Calculate the distance between two points using the Pythagorean theorem. Formula:
sqrt(pow(x2 - x1, 2) + pow(y2 - y1, 2)) - Loan Calculation: Calculate the monthly repayment of a loan. Formula:
P * r / (1 - pow(1 + r, -n))

Interactive FAQ
What is the difference between ‘==’ and ‘=’ in C?
‘==’ is the equality operator, used to compare two values. ‘=’ is the assignment operator, used to assign a value to a variable.
How can I check if a number is even or odd in C?
You can use the modulo operator ‘%’. If a number modulo 2 is 0, it’s even. Otherwise, it’s odd.
