Introduction to C++ Test Preparation
Course Introduction
Introduction to C++ is a foundational course aimed at students who wish to learn the basics of programming using the C++ language. The course covers fundamental programming concepts such as variables, data types, control structures, functions, arrays, and pointers. Students will develop problem-solving skills as they write, test, and debug simple C++ programs. Emphasis is placed on understanding object-oriented principles, including classes, objects, inheritance, and polymorphism, to prepare students for more advanced programming challenges. By the end of the course, learners will be equipped with a solid understanding of C++ syntax and essential programming techniques, enabling them to apply these skills in academic or professional settings.
