+            Class Attributes
+            You are the administrator of a hotel and must create customer information cards for your new customers. On the card, you must note the customer’s first and last name, age, and room number. 
+            The program you are given takes a guest's data (first name, last name, age, and room number) as input.
+            Complete the class by adding corresponding attributes so that the saveCustomerInfo() method works correctly. Also assign taken data values to attributes of created object.
+            Sample Input
+            John
+            Smith
+            35
