a class Music, which contains

• Three data members i.e. songTitle (of string type), singerName (of string type), and singingYear (of integer type)
• A no-argument constructor to initialize all data members with default values i.e. "---", "---", and 0, respectively
• A parameterized constructor to initialize all data members with user-defined values
• Three setter functions to set values for all data members individually

Derive a class named FolkMusic that contains

• A data field provinceName to hold the name of the province (of string type)
• A no-argument constructor to assign default value as "---" to provinceName
• A four argument constructor to assign user-defined values to songTitle, singerName, singingYear, and provinceName
• A setter function to set the name of the province
• A function named show() that displays all data member values of invoking object

a main() function that instantiates objects of FolkMusic class and test the functionality of all its member functions.

Please find the above C++ program. It has the Music class and FolkMusic class and main method to test these class.
