.insert()

Elements can be added to a map by inserting key-value pairs using the .insert() method.

A pair can be inserted using std::pair which is a class template used to store two different objects as a single unit.

mapName.insert(std::pair<type1, type2>(key, value));

Respectively, type1 and type2 are the data types of the key and value that will be inserted.

The following codebyte example inserts different mammals and their average lifespans into the lifeSpan map:
