1. Write a C# application that implements a class 'number" with the following functionality.
2. Three data members 'n', 'dsum' and 'rev' of integer data type.
3. Four public methods, readValues(),digitsum(), reverse() and dispResult()

i.readValues () - to accept the value of 'n' from the keyboard.

ii.digitsum () - to calculate the Digit sum of n.

iii.reverse () - to calculate the reverse of the number 'n'.

iv.dispResult() - to display the Digit sum and Reverse of 'n'.

In the Main method, create an object "N1" of the 'number" class, and calculate the Digit sum and Reverse using the above methods.[15 Marks]

Sample I/O

Enter a number : 1234

DigitSum = 10

Reverse = 4321
