Strings supposed to get stored in vector, then gets printed. It's not working...

[swoopsplat]

#include <iostream>
#include <vector>

using namespace std;

class Message {

public:
    Message ();
    Message (string, string, time_t);
    void changeSubject (string);
    void addMessage (string);
    void append();
    string getSender ();
    string getRecipient ();
    string getSubject ();
    string getMessage ();
    char* geTime ();
    void printEverything ();

private:
    string sender;
    string recipient;
    char* tstamp;
    string subject;
    vector <string> message;
};

void Message::addMessage (string messageo) {
message.push_back(messageo);
}

void Message::append () {
    int n = message.size();
    for (int x = 0; x < n; x++) {
        cout << message[x];
    }
return;
}

int main()
{
    Message person;
    string whatyouwant;
    cin >> whatyouwant;
    while (whatyouwant != "."){
        person.addMessage(whatyouwant);
        cin >> whatyouwant;
    }
   
    person.append();

    return 0;
}

The intention of my program is to take strings from the user and store them into a vector and later printing out the whole message by going through the entire vector and printing out the message one after another. The problem is, when I call the class function to print it, nothing gets printed. I'm not sure if it's even getting stored in the vector.

Please help, and thanks so much.
