Pointers, Arrays and Structures

In this assignment you will start a grand project ranging over four assignments. The purpose of the project is to design and build a database of phone book records implementing different topics covered in class.

Program guidelines:

· Design a struct type called Rec that will represent a record in your phonebook. The record will contain the following information: last name, first name and phone number (i.e. 3 fields).

· Use typedef to name your data type as Pb_Rec .

· The whole database will be represented by an array of 20 Pb_Rec type elements and will be called Phone_Book.

· Your program should perform the following operations, using at least three functions:

1 - adding records to the database interactively using appropriate messages.

2 - sort the database by last name.

3 - print the sorted database/phonebook.

· You should test your program with at least 5 records.

· Use pointer notation only, except for the declaration of Phone_Book, which should not be global and must be sent to your functions, i.e. passing arrays to functions.

· Do not forget to comment your program and follow the programming style guidelines discussed in class.

· You should hand in a cover page, source code and the output of your program.

Good luck !
