used to return the flow of control to the point where the procedure (also known as a function) was called and to return the value of expression.

Question 4

procedural abstraction

Answer 4

Extracting shared features to generalize functionality
Using parameters allows the functions (also called procedures) to be generalized.

Using procedural abstraction helps improve code readability.

Procedural abstraction manages complexity by allowing for code reuse.

For example: the function move(id, direction) could be used to move an element in any direction, rather than writing separate functions for each direction.
