design and testing programs

Question 1

what is structured programming?

Answer 1

involves decomposing the program into more manageable chunks or modules. these can then be decomposed into smaller tasks. an easy way of doing this is through subroutines.

Question 2

advantages of structured programming (4)

Answer 2

coding is easier because you’re only writing subroutines that carry out very simple individual tasks
multiple programmers can work on one program as each module can be written independantly
easier to test as each module can be tested independantly
individual subroutines or modules can be fixed and updated individually
