A : Its a default constructor that takes no
argument which is used to initialise the members of class . It is
used to initialise z1 = 2 and z2 = 4
B : We can see that the addition function is
overloaded, because the function name is same but the arguments is
different. addition function is overloaded with ( int, int) ,
(double, int) and (int, double)
C : we declare a class named as More_Poly that
extends Polynomial class so all the properties of base class
polynomial will be inherited by the child class More_Poly.
D: Inside the child class we redefine the base
class methods . This is known as Method Overrding. If the child
class want to redine parents class method, It can do so by
providing its own implemenation.Hence such constructs is known as
method Overriding.
E : We declare reference of type polymorphism
,
For the first polymorphism object, we declare its type and hence
approprioate methods will be called based on method
overloading
For the second object as binding will de decided at run time hence
appropriate methods wiull be called at run time

// Please follow all the instructions Each of the class declarations and/or member function definitions below has syntax error(s). Find every error. All errors with explanation and fix the code. * Hint: You may use compiler to help you find the error. However, you need to set up the program correctly and to point out the true cause of the syntax error. Because the compiler messages are convoluted, due to the convoluted nature of language dependencies. 54. class Truck, public...
