Welcome to this lesson on Maps and Multimaps in C++, integral parts of the C++ Standard Library. These associative containers like std::map and std::multimap are used to store key-value pairs, maintaining an organized order of elements. Understanding these containers enhances your ability to manage data efficiently in C++.

The std::map is a key-value pair container that maintains order based on keys. It ensures each key is unique and directly employs a binary search tree to manage this order. Here's how you can create and utilize a std::map to track fruit quantities:

A std::map provides numerous methods to manage and traverse its elements efficiently. Here are some key operations:
