Explain how problem decomposition helps in solving a programming problem. Use the task of preparing a student's result as an example and mention at least two smaller subtasks.

Answer: Problem decomposition means dividing a complex problem into smaller, manageable subtasks. For preparing a student's result, the subtasks could include accepting marks, calculating the total and average, assigning a grade, and displaying the result. Each subtask can be designed and tested separately before combining them into the complete solution.

Solution

Decomposition reduces complexity by breaking a large problem into simpler parts. Independent subtasks are easier to understand, implement, test, and combine into a complete solution.
