Introduction to Programming
Mock Exam
Course Introduction
Introduction to Programming is designed to provide students with a foundational understanding of computer programming concepts and problem-solving techniques. The course covers essential topics such as algorithms, variables, control structures (including loops and conditionals), data types, and basic data structures. Using a popular programming language, students will learn how to develop, test, and debug simple programs. Emphasis is placed on logic development, structured programming methods, and practical hands-on exercises to build computational thinking and prepare students for more advanced studies in computer science.
