Make a class with name(TerminalExam). Declare two variables i and j of type int in it. In constructor,

initialize these variable with values specified in parameters. Make a method named calculate in this class

of double return type. In this method, perform the addition of i and j and display the result. Make a second

class(SubC2) which inherits from first class (TerminalExam). In this class’s constructor, pass two values

as parameters but initialize the fields using superclass’s constructor. Override the method calculate()

defined in superclass. In overridden method, calculate the difference of i and j and print the result. Then

create a class in the same way for multiplication and division and override the method for multiplication

and division respectively. Make another class(Add3V) which extends TerminalExam. In this class, declare

a variable c of int type. In constructor of Add3V, call superclass constructor and then set value of c also. In

calculate method, first call calculate method of superclass. Then print the value of c.

use c# programming language.
