Introduction to Programming Exam Solutions
Course Introduction
Introduction to Programming provides students with a foundational understanding of computer programming concepts and problem-solving strategies. The course explores key topics such as algorithms, variables, data types, operators, control structures (loops and conditionals), functions, and basic data structures. Emphasizing hands-on practice, students use a programming language typically Python or Java to write, test, and debug simple programs. By the end of the course, students will have developed the skills necessary to design, implement, and analyze basic algorithms, laying the groundwork for more advanced studies in computer science and software development.
