INTRODUCTION

C++ is a statically typed, compiled, general-purpose, case-sensitive, free-form programming language that supports procedural, object-oriented, and generic programming. C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features.

C++ was developed by Bjarne Stroustrup starting in 1979 at Bell Labs in Murray Hill, New Jersey, as an enhancement to the C language and originally named “C with Classes” but later it was renamed C++ in 1983. C++ is a superset of C, and that virtually any legal C program is a legal C++ program. Object-Oriented Programming:- C++ fully supports object-oriented programming, including the four pillars of object-oriented development: Encapsulation:- Encapsulation is the mechanism that binds together code and the data it manipulates, and keeps both safe from outside interference and misuse. Data hiding:- The insulation of data from direct access by the program is called data hiding or information hididng. In other words, we can say that encapsulation is implmented through information hiding. Inheritance:- Inheritance is the process by which one object can acquire the properties of another object. This is important because it supports the concept of classification. If you think about it, most knowledge is made manageable by hierarchical classifications. Polymorphism:- Object-oriented programming languages support polymorphism, which is characterized by the phrase "one interface, multiple methods." In simple terms, polymorphism is the attribute that allows one interface to control access to a general class of actions.

WORKING DESCRIPTION This program is designed to keep the friend’s record.

This program consists of FIVE options as follows 1.addition of new record 2. display all records 3. search a record by telephone no. 4. search a record by fname 5. search a record by lname 6. search a record by street 7. search a record by city 8. search a record by state 9. deletion of telephone no. 10. exit
