10 Captivating Programming Challenges to Boost Your Coding Skills 💻

Embark on an exciting journey of programming mastery with this curated collection of 10 captivating challenges from the LabEx platform. Whether you're a beginner looking to hone your skills or an experienced coder seeking new intellectual stimulation, this diverse set of exercises will push the boundaries of your coding prowess. 🚀

1. Output the Square Root 🔢

In this challenge, you'll write a C program to calculate the square root of a positive number less than 1000. The program should prompt the user to enter a number and then output the integer part of its square root. If the input number is not within the valid range, the program should ask the user to re-enter the number. Try it now!

2. Check Even or Odd 🌟

Dive into this lab and create a program that checks whether a given number is even or odd, and then prints the corresponding result. A simple yet essential skill for any budding programmer. Explore the challenge!

3. Miles to Kilometers Conversion 🌍

In this lab, you'll convert a distance in miles to kilometers using a provided formula and display the result. Mastering unit conversions is a valuable asset for any programmer working with real-world data. Start the challenge!

4. Implementing Armstrong Number Checker 🔍

This lab tasks you with creating a function that displays Armstrong numbers between two intervals. You'll need to check if the sum of the cubes of each digit in a number is equal to the number itself, and then implement this function in the main function where you get input values and iterate through the given range. Dive in!

5. Implementation of Complex Calculator 🧮

In this lab, you'll create a program that overloads the +, -, *, and / operators to perform complex arithmetic calculations. You'll use a Complex class with real and imaginary variables, and then conduct the appropriate arithmetic operation based on user input, displaying the result in the format 'real + imagi'. Explore the challenge!

6. Calculate Profit and Profit Percent 💰

Dive into this lab and create a program that calculates the profit and profit percent given the cost price and selling price, where the selling price is assumed to be greater than the cost price. Mastering this skill will be invaluable for any future business-related projects. Start the challenge!

7. Redefining Energy Calculation Macro 🔬

In this lab, you'll redefine a macro to solve Einstein's famous equation using two different values of the speed of light, calculate the energy with the given mass using the macro, and print the results. Exploring the power of macros and their applications is a valuable skill for any programmer. Dive in!

8. Implement Protected Inheritance 🏆

In this lab, you'll create a program that implements protected inheritance by creating classes Person and Employee, where Employee is derived from Person. You'll then create an object of the Employee class to print the values of the name and address variables. Mastering inheritance concepts is a crucial step in your object-oriented programming journey. Explore the challenge!

9. Determine Perfect Number Existence 🔍

In this lab, you'll create a function to check whether a given number is a perfect number or not by finding the sum of its positive divisors and comparing it with the initial number. Delving into number theory problems like this will sharpen your problem-solving skills. Start the challenge!

10. All Possible Permutations for Borrowing Books 📚

In this challenge, you'll write a C program that displays all possible lending methods and counts the total number of unique lending configurations when James must lend 5 new books to three friends—A, B, and C—with each borrowing only one book at a time. Tackling combinatorial problems like this will hone your algorithmic thinking. Dive in!
