Using the map ADT

Operations:
Create empty map
Find key in map
Find value of a given key, if key exists
Insert a key with its associated value, if key does not already exist
Remove a key and its associated value

Implement map ADT in file called mapChegg.java, to map email addresses (String, key) to people's names (string, value).

Your driver class should add at least 3 people, search for 2 people by key (email addresses) and remove all keys when done.

Here you define a class Map, decide how you are storing key, value pairs

Then have a Map() constructor, a method returning a boolean called findKey, a method returning the value of a given key getValue(key) if the key exists, ...

Then you will make a MapTester file.

Explanation / Answer

void mapAll(void (*fn)(KeyType, ValueType)) const;
void mapAll(void (*fn)(const KeyType&, const ValueType&)) const;
void mapAll(FunctorType fn) const;
Iterates through the map entries and calls fn(key, value) for each one. The keys are processed in an undetermined order.

Usage:

map.mapAll(fn);
void remove(KeyType key);
Removes any entry for key from this map.

Usage:

map.remove(key);
