• Show built-in types available for use in your solution.
• Introduce classes as a means of creating your own types and abstractions.
• Examine an array of ready-made patterns.
FINDING PATTERNS IN PROGRAMS
Finding patterns during problem decomposition was first mentioned in Chapter 3, in ‘Patterns and generalisation’.
