(output)
Control Structures - Answer-Instructions that determine the order in which other
instructions in a program are executed
op-Down Solution - Answer-decomposes a general solution into more concrete
solutions to sub-problems

-Filtering
-Scenarios
- Responsibilities
Object-Oriented Design - Answer-a problem-solving methodology that produces a
solution to a problem in terms of self-contained entities called objects
