Programming Logic and Design
Mock Exam
Course Introduction
Programming Logic and Design introduces students to the foundational concepts and techniques used in computer programming and problem solving. Emphasizing structured programming, algorithm development, and flowcharting, the course covers key logical constructs such as sequence, selection, and iteration. Students learn how to analyze problems, design step-by-step solutions, write pseudocode, and create flowcharts to visually represent algorithms. The course serves as a vital precursor to actual coding by reinforcing the importance of logical thinking, clarity, and precision in designing computer programs, ensuring students are well-prepared to progress to study in specific programming languages.
