Q$2.(70$ marks$)$ Social Media Platform Simulation. Design a system that simulates a basic social media

platform where users can create profiles, post content, and interact with other users$$ posts by liking and

commenting. You need to create three classes: User class, Post class, SocialMediaPlatform class. The

requirements for each class are as follows.

$1.$ User Class represents each user on the platform, with profile information and a list of posts. It has the

following attributes: userID$($int$,$ a unique identifier for each user.$),$ username$($string$),$ bio $($string$,$ a brief

description of the user.$),$ posts $($vector of Post objects containing a list of the user$$s posts.$)$

It has the following Member Functions:

$1)$ Get and set functions for username;

$2)$ createPost $-$ Creates a new Post and adds it to the posts list.

$3)$ listPosts $-$ Prints all posts by the user, displaying post IDs, content, likes.

$2.$ Post class represents individual posts created by users. Each post includes content, a count of likes, and

comments from other users. It has the following attributes: postID $($int$,$ A unique identifier for each post$),$

content $($string$,$ The content of the post$),$ likes $($int$,$ Number of likes the post has received$),$ comments $($vector

of string, A list of comments on the post$).$

It has the following Member Functions:

$1)$ addLike $-$ Increments the likes count.

$2)$ addComment $-$ Adds a comment to comments.

$3)$ viewPost $-$ Displays the content, number of likes, and all comments.

$3.$ SocialMediaPlatform class manages the entire platform, including user registration, post creation, and user

interactions. It has the following attributes: users $($vector of User objects, A list of all registered users$).$

It has the following Member Functions:

$1)$ registerUser $-$ Adds a new User to the platform by taking username and bio as input. Whenever register

a new user, a userID should be set as well. The userID is not input by the user, instead it is assigned by

the program. userID should be unique without repetition.

$2)$ removeUser $-$ Removes a user by userID.

$3)$ findUserByUsername $-$ Returns a pointer to a User given the username.

$4)$ createPostForUser $-$ Allows a specific user to create a post.

$5)$ likePost $-$ Increments likes for a specific post by a specific user.

$6)$ commentOnPost $-$ Allows a user to comment on another user's post.

$7)$ viewUserProfile $-$ Prints a user$$s profile with posts, likes, and comments.Requirements:

$1)$ Create a file called user.h for the User class definition.

$2)$ Create a file called post.h for the Post class definition.

$3)$ Create a file called socialmediaplatform.h for the SocialMediaPlatform class definition.

$4)$ Implement each class in separate files: user.cpp$,$ post.cpp$,$ and socialmediaplatform.cpp$.$

$5)$ Write a main function in a file called ssocialmedia$\_$test.cpp to do the following:

$$ Prompt the user to create multiple users.

$$ Allow users to create posts, like posts, and comment on posts.

$$ Display user profiles and test all member functions.
