#include <iostream>

    std::cout<<"Megan Fox is the hottest girl!"<<std::endl;
}

you forgot to return 0

//------------------------------------------------------------------------------------------------------------------------// START   //
    do {                                                                                                                  // Do While -
        cin >> HottestGirl;                                                                                               // Input
        if (HottestGirl == 1) {                                                                                           // Set Case If
            cout << "\nClaudia Lynx is the hottest girl!\n\n";
        }
        else if (HottestGirl == 2) {                                                                                      // Set Case If
            cout << "\nMegan Fox is the hottest girl!\n\n";
        }
        else if (HottestGirl == 3) {                                                                                      // Set Case If
            cout << "\nAudrina Patridge is the hottest girl!\n\n";
        }
        else {                                                                                                            // If none above then do
            cout << "Invalid Selection\n\n";
        }
    } while (HottestGirl == 0);                                                                                           // Do the above while HottestGirl equals 0


}

hmm... I understand that except for the last part where it says:

Code:

    } while (HottestGirl == 0);

What is this there for?
Also, one thing this doesn't do is display "Selection: " before the user inputting the selection. Is there a way to fix this or no? It's not that it's so important, the program means nothing, I am just trying to learn

You need to put effort into getting a book, because loops is one basic thing all programmers must know.
If you don't have one, I would recommend getting Accelerated C++.
This loop simply says: loop WHILE HottestGirl equal 0.
