implementing this function for me. void rentMovie(std::string title);

2. rentMovie method: When the user calls this method you need to update the quantity in stock property of the movie, then display the new information about the movie. If the movie is not found, your program should display, Movie not found. If the movie is found in the tree but the quantity is zero, display Movie out of stock.. Information about the movie rented should be printed from within the rentMovie method.

Rent a movie menu option: When the user selects this option, they should be prompted for the name of the movie. This title should then be used to call the rentMovie() method.

parent node is not defined in hpp, dont give me the answer with it.

Thanks
