// 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.
