Reviews

Object-oriented programming (OOP) has been around for decades. As the original object-oriented language, C# is a mainstay in the world of computer programming. All the concepts of object-oriented programming that C# developers love to have in their arsenal are explained in detail along with relevant coding examples and exercises in this course. This course is unique in its nature as it follows a project-based learning approach. Throughout the course, a real-world example of vending machine is followed to help the learners develop a firm understanding of the stated OOP concepts. The learners will not only be able to play around with the project, they’ll also be able to see all the concepts in action in this project.
