    Well there's your mistake. The op had a big problem with his conditions earlier, so if I was going to post an answer in code, I would do my best to make sure the conditions worked. Yours don't, so I made a comment.

    Or you could refactor away all the junk and just go with:
    Code:
    #include <iostream>
    
    int main() {
        std::cout<<"Megan Fox is the hottest girl!"<<std::endl;
    }

    C++ does not require an explicit return statement from main.

    A return statement in main has the effect of leaving the main function
    (destroying any objects with automatic storage duration) and calling
    exit with the return value as the argument. If control reaches the
    end of main without encountering a return statement, the effect is
    that of executing
    return 0;

                cout << "\nClaudia Lynx is the hottest girl!\n\n";
            }
            else if (HottestGirl == 2) {                                                                                      // Set Case If

            }
            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.

    Outside of your DOS world, your header file is meaningless.
