Object-Oriented Programming Pre-Test
Questions
Course Introduction
Object-Oriented Programming introduces the fundamental principles of designing and implementing software using the object-oriented paradigm. The course covers core concepts such as classes, objects, encapsulation, inheritance, polymorphism, and abstraction. Students will learn to structure code for modularity and reusability, develop problem-solving skills using object-oriented methodologies, and gain practical experience through programming assignments and projects in a modern object-oriented language such as Java or C++. By the end of the course, students will be able to analyze problems, design object-oriented solutions, and implement efficient programs that demonstrate best practices in software development.
