Programming Logic and Design Exam Solutions
Course Introduction
Programming Logic and Design introduces students to the foundational concepts of computer programming and problem-solving using logical approaches. The course covers essential topics such as algorithms, flowcharts, pseudocode, control structures (sequence, selection, repetition), and modular programming. Students will learn how to systematically analyze problems, develop step-by-step solutions, and translate them into basic program designs, preparing them for success in any programming language. Emphasis is placed on developing analytical thinking, understanding logical flow, and applying structured techniques to design robust, maintainable programs.
