Object-Oriented Programming with C++

Course details

Are you an intermediate-level programmer looking to level up with C++? This comprehensive course is designed to equip you with a deeper understanding of some of the core principles of object-oriented programming (OOP) and their practical application in C++ development. Instructor Károly Nyisztor shows you what it takes to master encapsulation, inheritance, polymorphism, and abstraction, while gaining hands-on experience in designing and implementing C++ classes. Explore the proper use of constructors, destructors, and member functions, as well as advanced techniques for creating flexible and reusable code through inheritance and polymorphism. Along the way, discover essential memory management strategies, including the use of smart pointers and RAII principles, to write more efficient and robust C++ programs.

Learning objectives
Explain the core principles of object-oriented programming (encapsulation, inheritance, polymorphism, and abstraction) in the context of C++.
Design and implement C++ classes, including proper use of constructors, destructors, and member functions.
Apply inheritance and polymorphism to write flexible and reusable C++ code.
Demonstrate proper memory management techniques using smart pointers and RAII principles in C++.
Design and develop small-scale object-oriented projects in C++, leveraging OOP concepts and C++-specific features.
