Alogarithm steps:

1. Start the program
2. Create the class
3. Declare the data member as array and member function
4. Get the input and store it in an array
5. Create the object for the class
6. Call the function by using of the object
7. The function perform the operation using the array data members
8. Compile and execute the program
