cpp map insert

The C++ map insert function is used to add a new key-value pair to the map. Here are the steps involved in the map insert:

1. Provide the key and value that you want to insert into the map.
2. Use the insert function to add the key-value pair to the map.
3. If the key already exists in the map, the insert function will not add a new key-value pair.

That's the explanation for using the C++ map insert function.
