Social Media Assignment Solution with C++

Social Networking Site Problem

Background

A social networking site is an online platform that people use to build social networks or social relationships with other people who share similar personal or career content, interests, activities, backgrounds, or real-life connections.

For this project, we are going to create a simple social networking application for an organization with up to 100 people. Each person can then become friends with those people in the organization.

Person Data (provided in proj2_data.txt):

Emi, Carson, 23, 8370814

• First name (string)
• Last name (string)
• Age (int)
• ID (int)

Assignment Description

Initially, you should work to write the functions in the Person class. A Person is made up of the data listed above and an array of Friends. Every Person is limited to the maximum number of friends defined by the constant MAX_FRIENDS. The Person class will be used repeatedly when the roster is loaded into the Organization. An Organization is made up of a roster that is limited to the constant MAX_PEOPLE. The FriendFinder class manages the Organization and provides the menu interface for the application.
