Thread: Structure Diagrams??

Never used structure diagrams before but now I need to for an assignment - anybody any tips? For example - how much detail do you include? If you are incrementing a variable how specific do you need to be on the chart?

Here's the problem - all suggestions welcome:

The program is to cope with input of an unspecified number of exam marks (the number to be input and validated at run time)

Marks must be in range 0 - 99 and they must be validated on input. When all have been input the following stats must be output:

Number of students marks entered

The mean mark of all students

The range of marks

The number of students achieving each grade:

fail <39
pass 40-64
merit 65-74
distinction 75+

In addition the marks should be recorded against the grouped range into which they fall and the mode group output.

I can code it but the diagram?? help appreciated

> how much detail do you include?
Hard to say - here are some ideas

What are the local standards - given this is an assignment, ask the marker. An example from an un-related project (design and code) would be helpful.

How inherently complex is the task - the more complex the task, the more detail you would want to add.

Who's doing the implementation after the design - if it's someone else, you would want to add more detail.

What is the life of the program - will it require maintenance? - If so, then more detail might be better.

I would say that one box/circle/whatever on the chart should equate to at most 5 lines of code (you estimate).
