## 1. Calculate Simple Interest Using Function 💰

[Lab URL](https://labex.io/labs/113825)

In this lab, you'll create a program that calculates simple interest using a function called `simpleInterest()`. This function takes three double arguments representing the principal, time, and rate, and returns the calculated simple interest. By mastering this challenge, you'll gain a deeper understanding of function implementation and the application of mathematical concepts in programming.

## 2. Create a Simple Stopwatch App Using GTK (Challenge) ⏱️

[Lab URL](https://labex.io/labs/299437)

Dive into the world of GUI programming as you learn how to use the GTK library in C to create a simple stopwatch application. This challenge will guide you through the process of building a stopwatch with start/pause and reset buttons, allowing you to explore the intricacies of event handling and user interface design.

## 3. Swap Two Numbers using Temporary Variable 🔁

[Lab URL](https://labex.io/labs/113913)

In this lab, you'll create a program that swaps the values of two variables using a temporary variable. This seemingly simple task is a fundamental concept in programming, and mastering it will strengthen your understanding of variable manipulation and logical thinking.

## 4. Finding the Greatest Common Divisor 🔢

[Lab URL](https://labex.io/labs/113863)

Dive into the realm of mathematical algorithms as you create a program that finds the Greatest Common Divisor (GCD) of two numbers using a function called `findGCD()`. This challenge will introduce you to the Euclidean algorithm, a powerful technique for efficiently determining the GCD of two integers.

## 5. Sum All User Inputs 🧮

[Lab URL](https://labex.io/labs/113818)

In this lab, you'll create a program that finds the sum of all user inputs until the user enters 0. This exercise will hone your skills in handling user input, implementing loops, and performing basic arithmetic operations, preparing you for more complex programming tasks.

## 6. Fahrenheit to Celsius Converter 🌡️

[Lab URL](https://labex.io/labs/113832)

Explore the world of unit conversions as you create a program that takes a temperature in Fahrenheit as input, converts it to Celsius using the formula `(celsius = (fahrenheit - 32) * 5 / 9)`, and prints the Celsius temperature. This lab will help you understand the importance of data transformation and the application of mathematical formulas in programming.

## 7. Finding Prime Numbers in a Range 🔍

[Lab URL](https://labex.io/labs/113898)

Dive into the realm of number theory as you create a function to find all the prime numbers between two intervals. This challenge will require you to implement a loop to access each element between the given range, and pass each value to a function `isPrime()` that checks if a number is divisible by any number from 2 to the number itself. Mastering this lab will strengthen your problem-solving skills and your understanding of prime number identification.

## 8. Calculating Rectangle Area 📐

[Lab URL](https://labex.io/labs/113820)

In this lab, you'll write a program that takes user inputs for the length and breadth of a rectangle, and calculates the area by multiplying the length and breadth values. This seemingly simple task is a fundamental concept in programming, and mastering it will prepare you for more complex geometric calculations.
