Overload the stream extraction operator >> for the class Address defined in question 1 to input an object of class Address either from the keyboard or from a file. Also overload the stream insertion operator Use separate compilation to convert class Address to an ADT. Then write an application program that requests the user to specify a postal code and uses the overloaded extraction operator >> to extract Address objects one by one from a file named Address.dat. Compare the postal code supplied by the user to the postal code of each object extracted from the file. If the postal codes are the same, put the object into an array of Address objects. Assume that the array will never need to contain more than 20 Address objects. Once all the 46 objects have been extracted from the file and compared to the user-specified postal code, use the overloaded insertion operator Use the following data for the file Address.dat: Hope St 67 Clarence 0917 Nelson Mandela Drive 643 Pretoria 0181 Albert St 91 Pretoria 0181 Church St 14 Wellington 6734 Main St 907 Soweto 0912 Bushbuck St 89 Polokwane 3452 If the user input 0181 as the postal code, your program should display the two addresses in Pretoria on the screen. Enrichment exercise: Adapt the application program to use a vector instead of an array. It should not be necessary to
