Maps

Maps provide a data structure that allow for the storage and management of key/value pair data.

Notes

Maps provide a way to store and retrieve key/value pairs.
The map key must be a value that can be used in an assignment statement.
Iterating over a map is always random.

Exercises

Exercise 1

Declare and make a map of integer values with a string as the key. Populate the map with five values and iterate over the map to display the key/value pairs.
