The cpp unordered_map.erase function is used to remove elements from an unordered map data structure in C++. It takes in a key parameter and deletes the corresponding key-value pair from the unordered map. If the key is found, the erase function returns the number of elements removed (which is always 1 since unordered maps don't allow duplicate keys). If the key is not found, the erase function returns 0. This function helps in dynamically managing the elements of an unordered map by allowing easy removal of specific key-value pairs.
