Computer Science for IGCSE & O level - Algorithm Design And Problem Solving (Section 2 - No. 27)

What is the primary purpose of a structure diagram in the context of algorithm design?

To display the algorithm's flow in a user-friendly format.

To help in understanding the algorithm's data structures.

To visualize how the program will be structured as a combination of sub-problems.

To convert the program to a high-level programming language.

A structure diagram is used to help create a system of sub-programs as part of the main program.
