.insert()

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

Syntax

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.
