Programming Fundamentals
Exam Answer Key
Course Introduction
Programming Fundamentals introduces students to the essential concepts and techniques of computer programming. The course covers key topics such as variables, data types, control structures (conditionals and loops), functions, and basic input/output operations. Students learn problem-solving strategies, algorithm development, and the principles of structured programming using a high-level programming language. Through hands-on exercises and assignments, learners gain practical experience in writing, testing, and debugging simple programs, laying a strong foundation for more advanced studies in computer science and software development.
