C++ remains the backbone of high-performance computing, systems programming, and game development. For beginners, the journey from basic syntax to complex data structures can feel daunting. This curated selection of hands-on labs from the LabEx C++ Learning Path bridges that gap, offering a practical roadmap to master conditional logic, character manipulation, and dynamic memory management through real-world problem-solving.
Output the Maximum Value
Difficulty: Beginner | Time: 5 minutes
In this challenge, you are asked to write a C program that takes three integer values as input and outputs the maximum of the three. The program should use the scanf function to handle keyboard input and implement the logic to determine the maximum value.

Output the Encrypted Letters
Difficulty: Beginner | Time: 5 minutes
In this challenge, you are asked to write a C program that translates the word 'LabEx' into an encrypted password. The encryption rule is to replace each letter with the 4th letter after the original letter. You will use both the putchar and printf functions to output the 5 encrypted characters.

Output the Last Serial Number
Difficulty: Beginner | Time: 5 minutes
In this challenge, you are asked to write a C program that simulates a group of 13 people standing in a circle. Starting from the first person, they count 1, 2, 3 in order, and the ones who reach 3 will leave the circle. The goal is to find the serial number of the last person remaining in the circle, and implement this using a linked list.
