100 C++ Coding Challenges: Practice, Improve, Master!

A Complete Journey from Fundamentals to Advanced Projects with Modern C++ (C++98 to C++20)

What you'll learn

Master the fundamentals of C++ programming

Apply modern C++ features to solve real-world problems

Build practical, hands-on coding experience through 100 structured exercises

Design and implement complete C++ applications using professional techniques

Requirements

No prior programming experience is required—just basic computer skills and a strong motivation to learn C++.

Description

100 C++ Coding Challenges: Practice, Improve, Master! is a comprehensive, hands-on course designed to take you from a complete beginner to an advanced C++ programmer. Whether you're a student, aspiring developer, or a professional looking to sharpen your C++ skills, this course offers a structured and practical path to mastering modern C++ through 100 carefully crafted coding challenges.The course is divided into 10 progressive levels, covering everything from the basics of input/output, variables, and control structures (C++98/C++03), to more advanced concepts like pointers, object-oriented programming, STL, templates, file handling, multithreading, and design patterns (C++11–C++20).Each session includes a clear theory guide, followed by real-world exercises and mini-projects that reinforce the concepts in a meaningful and applied way. You’ll build everything from a basic calculator and student gradebook to a multithreaded restaurant simulation and a stock trading dashboard using design patterns.By the end of this course, you'll have solved 100+ coding exercises, built reusable C++ systems, and developed a solid portfolio of projects. Most importantly, you'll gain the confidence to tackle interviews, technical tests, and real-world software challenges with modern C++.No prior experience is required—just your motivation to learn, solve problems, and become fluent in one of the most powerful programming languages in the world.
