int factorial(int a) : returns the factorial of a number
(factorial of n = 1 × 2 × 3 × ..... × n)
void display ( ) : displays the data members
Class name : Series
Data member/instance variable :
sum : to store the sum of the series
Member functions/methods :
Series(...) : Parameterized constructor to initialize the data members of both
the classes
void calsum( ) : calculates the sum of the given series
void display( ) : displays the data members of both the classes
