In C#
Write a ZipCode class using Main. Your ZipCode class will encode and decode five digit bar codes used by the US Postal Service on envelopes. The class should have two constructors.
The first constructor should input the zip code as an integer o If it has less than 5 digits, just assume that any missing digits are leading 0s o If it has more than 5 digits display an error message.
The second constructor should input the zip code as a bar code string consisting of 0s and 1s as described above. o It should check for various errors and report them. The output sample illustrates several errors that must be reported.
Although you have two ways to input the zip code, internally the class must only store the zip code as an integer value. The bar-code representation can always be reconstructed from the integer value.
TheZipCode class should also have a public method, GetBarCode() to return the zip code as a properly constructed string of binary digits.Or else report a specific error.
This class should use a Property for zip similar to the treatment of balance in Account.cs (Please see Startup Notes 4). Notice in this implementation that it is easily possible to check that the zipcode value is no more than 5 digits. (The Property feature of C# avoids the need for extra methods such as GetZip and SetZip (And similar method names if there are additional member variables of classes.) This feature is not \ available in Java.
You also need a private method ParseBarCode()to decode the string of binary digits and return the bar code value as an int. This is the most complicated method of the assignment
