Introduction to Programming
Pre-Test Questions
Course Introduction
Introduction to Programming is a foundational course designed to familiarize students with the core concepts and techniques of computer programming. Through a hands-on approach, students will learn how to write, test, and debug simple programs using a modern programming language. Key topics include variables, data types, control structures (such as loops and conditionals), functions, and basic data structures. By the end of the course, students will have developed problem-solving skills and a fundamental understanding of how software is created, laying the groundwork for further study in computer science and related fields.
