Chapter 16 – Creating and Using More Complex Structures

1. The compositions are as follows:
   1. Card is a simple structure of intrinsic and enumerated types.
   2. Hand is a structure that consists of an array of pointers.
   3. Deck is a structure that consists of an array of structures, an array of pointers, and intrinsic types.
2. Stepwise refinement. Each step in the process takes a working program and adds features to it until the desired program is complete.
3. Magic numbers are literal values that have special significance that represent real-world meaning. While magic numbers are a natural part of things we represent in our programs, we should strive to give added meaning to those numbers through the use of constant variables, enumerated constants, and preprocessor symbols.
4. In one case, enumerated constants for Face and Suit that are related to each other use the e- prefix. In the other case, enumerated constants for array sizes are unrelated and use the k- prefix.
