Practical problem solving in heritance with oop in cpp/c++

/*
Write a program in C++ with the following description:
Create three classes “CPP”, “PYTHON”, and “JAVA” with 
Private Data Members: Invention_Year, Invented_Country.  
Public Member Functions: A parameterized constructor to 
take and assign values to the data members and print those values.
Inherit the “CPP”, and “PYTHON” classes from the “JAVA” class.
Now test the program by creating an object of the “JAVA” class.
