2.1.3 Thinking Procedurally

Question 1

What is the first stage of thinking procedurally in software development?

Answer 1

Problem decomposition

Question 2

What is problem decomposition?

Answer 2

Breaking down of a large, complex problem down into smaller subproblems that can be solved more easily

Question 3

Why is problem decomposition used?

Answer 3

Projects become easier to manage
Can be divided between a team

Question 4

Describe top-down design / stepwise refinement.

Answer 4

Problems broken down into subproblems until each is a single task
Problems divided into levels of complexity
Each subproblem can be solved using single subroutine

Question 5

Why can subroutines be described as self-contained?

Answer 5

Can be developed & tested separately

Question 6

What type of problems is stepwise refinement suited to?

Answer 6

Large, complex problems

Question 7

What is the second stage of thinking procedurally in software development?

Answer 7

Identifying components of a solution

Question 8

What considerations need to be made when recombining solution components?

Answer 8

The execution order of subroutines
How subroutines interact
