Introduction to Programming Question Bank
Course Introduction
Introduction to Programming provides students with the foundational knowledge and practical skills necessary to begin developing computer programs. Through hands-on exercises and guided instruction, students learn core concepts such as variables, control structures, loops, functions, and basic data structures using a contemporary programming language. Emphasis is placed on problem-solving techniques, logical thinking, and writing clear, well-documented code. By the end of the course, students will be able to design, implement, and test simple programs, preparing them for more advanced studies in computer science and related fields.
