Program Plan Intro
Checking Validity of Social Number
- Include the required header files.
- Declare the prototype of the function isValidSocialSecurityNumber.
- Define the “isValidSocialSecurityNumber()” function.
- Check whether str1.length()!=11 or str1.find_first_of("-")!=3 or str1.find_last_of("-")!=6.
- If so then return false.
- Traverse through str1.
- If i is ‘-‘ at locations 3 or 6 then continue.
- If the traversed character is not a digit then return false.
- Return true.
- Define the “main()” function
- Create a string variable s and assign the social security number to it.
- Make a call to function isValidSocialSecurityNumber with s and assign to ans.
- If value of ans is 1 then display valid message.
- Else display invalid message.

When the decorated function is invoked, this decorator should modify the arguments the decorated function receives. This decorator should filter out all positional arguments passed to the decorated function, which are found in the positional arguments passed to the decorator when the decorator was initialized. It should also filter out all keyword arguments with keys that are found in the keyword arguments given to the decorator when the decorator was initialized.

The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…arrow_forward
