Write a Twitter class that sets the Twitter user first (who is to be followed) and lets the client add up to 5 followers, which will be stored in an array with a capacity of 5. These users/followers could be in the form of string or Profile. (Note that the followers are not stored as users, but as strings or Profiles).
At any time, your main program should be able to remove any user, x from following another user, y (i. e., x is no longer in the array of followers of y).
You are free to design your program as you wish as long as you fulfill the following requirements:
Twitter class should be declared as a template class (the template parameter defines how the followers are represented)
Twitter class includes a constructor that initializes the name of the user that is passed. The number of followers starts off at 0.
AddFollower function in Twitter class should be defined correctly. It takes as parameter an object of the template parameter.
RemoveFollower function in Twitter class should be defined correctly. It takes as parameter an object of the template parameter.
PrintFollowers function in Twitter class should be defined correctly. It displays the name of all the followers. (Remember: each follower is an object of the template parameter. As you will declare Profile struct which can be a template parameter, for the Profile struct, we must overload stream insertion << operator. Now, we can use cout << follower to display the follower).
Submitting a main program that tests the Twitter class as follows:
Twitter object
Twitter object
Whenever any change is made to a Twitter object (like a follower is added, a follower is removed), call PrintFollowers to display the followers of the Twitter object.
