How To Make An Address Book In C++ Using Ios::app

C++ project on address book using classes and file handling is one of the simplest C++/ C project to demonstrate the working of a computer Project. This project was actually demonstrated in Class room – How to create a computer Project using all the acquired knowledge.

This project uses a simple class Telephone and one data file 'telephone.dat' . Here is the sample code of this project. We missed some functions from this project as the same should be prepared by the student in order to fully understand the working of this project.

for better understanding on File handling in C++, You can have our notes on file handling and assignments and some high level file handling programs in C++.
