Programming Fundamentals
Exam Materials
Course Introduction
Programming Fundamentals introduces students to the core concepts of computer programming, focusing on structured problem-solving and the design of efficient algorithms. Through hands-on experience, students learn the syntax, semantics, and logic of a programming language, typically including variables, data types, control structures, functions, and basic input/output operations. The course emphasizes developing computational thinking skills and debugging techniques, preparing students for more advanced studies in computer science and software development.
