TMap is a container in C++ that allows key-value pairs to be stored based on unique keys. The FindOrAdd function in TMap is used to find a value associated with the key. If the key is not found, a new key-value pair is added to the map. This function is useful when adding items to a map, as it avoids the need for extra checks.
Example 1: Suppose we have a TMap called "student_grades" where the key is the student's name and the value is their grade. We can use the FindOrAdd function to find a student's grade, or add a new student and their grade if they are not already in the map.
Code:

Example 2: Suppose we have a TMap called "inventory" where the key is a product code and the value is the number of items in stock. We can use the FindOrAdd function to add items to the inventory, or update the quantity if the product code already exists in the map.
