Responsibility Algorithms for AddressDr: We have prepared enough files for both input

and output by now to consider these responsibilities concrete. “Process entries” implies

more than one entry, which implies a loop. Let’s instruct the user to enter “Quit” for the

first name when all of the entries have been processed.

Now all of the steps in “Process entries” are concrete.

Enter phone

Write "Enter area code: "

Read and convert area code to int

Write "Enter number: "

Read and convert number to int

Enter address

Write "Enter street address: "

Read street

Write "Enter city: "

Read city

Write "Enter state: "

Read state

Write "Enter ZIP code: "

Read zip

Enter rest of name

Write "Enter last name: "

Read last

Write "Enter middle name: "

Read middle

Process entries

Write "Quit entered for the first name ends the application."

Write "Enter first name: "

Read first

while(name is not equal to "quit")

Enter rest of name

name = new Name(first, last, middle)

Enter address

address = new Address(street, city, state, zip)

Enter phone

phone = new Phone(areaCode, number)

entry = new Entry(name, address, phone)

entry.writeToFile(outFile)

Read first

close files
