programming-examples/c++/Overview/CPP Program To Implement Multiple Inheritance and also Passing Parameters To Base Class Constructors.cpp

// step 1:  Declare the base class namely BaseClass1. It consists the private member data and a constructor.

// Step 2:  Declare the base class namely BaseClass2. It consists the private member data and a constructor.

// Step 3:  create the derived class namely DerivedClass from BassClass1 and BaseClass2.

// Step 4:  Declare constructor in DerivedClass with three arguments and also base  the arguments to base class constructor.

// Step 5:  Create the object for DervidClass in main ().

// Step 6:  The object automatically call the Derived class constructor. Now Derived class constructor automatically call the baseclass1 & baseclass2 constructor with arguments.

// Step 7:  Display the values.
