6.8. Chapter Summary¶

This chapter included the following concepts from computing.

Bottom up implementation - The process of building a program by first building small low-level, simple procedures and then using those to help build more complex procedures.
Precondition - Something that the code in a procedure assumes to be true. The caller of a procedure is responsible for making sure the Precondition is true before calling it.
Top down design - The process of breaking a complex task into smaller problems that are easier to solve.
