Imperative Programs

Array of integers example
Write a program that stores the integer marks of a student for several items of assessment, each of equal value. The program outputs the total and average mark.
A Monolithic Solution
- Marks.cpp - Marks program, version 1 (Monolithic)
A Library Solution
- An integer array library for the Marks program
  - intarraylib.h - Integer array library header, version 1
  - intarraylib.cpp - Integer array library implementation, version 1
- MarksLib.cpp - Marks program, version 2 (Library)
Problems with these Solutions
- User has to use (unfriendly) 0 ... indexing of arrays
- Number of items is the user's responsibility
- Marks can be directly changed
Using structs
- MarksStruct.cpp - Marks program with structs (Monolithic)
- Smart library solution - Lab work
- But the problems are not all gone (which remain?)
A Class Solution
- smartintarrayclass.h - Smart integer array class header
- smartintarrayclass.cpp - Smart integer array class implementation
- MarksClass.cpp - Marks program (Class)
