Why wont this work!? (C++)

So I have been trying to write the basics of a Blackjack program in C++, but I keep getting this error. error C4716: 'handGenerator::playerHand1' : must return a value
Here's the code

#include "stdafx.h"

#include <iostream>

#include <string>

#include <cstdlib>

#include <ctime>

using namespace std;

class handGenerator{

public:

int playerHand1()

{

int aceChoice;

int cardPlayer1 = rand()%13;

switch (cardPlayer1) {

case 1:

cout << "You have an Ace, do you want it to be 1 or 11?" << endl;

cin >> aceChoice;

break;

case 11:

cardPlayer1 = 10;

break;

case 12:

cardPlayer1 = 10;

break;

case 13:

cardPlayer1 = 10;

};

cout << "Your hand is" << cardPlayer1;

}

};

 

int main() {

 

cout << "Welcome to Richard's game of Blackjack!" << endl;

cout << "What's your name?" << endl;

string name;

cin >> name;

cout << "Hi " << name << endl;

handGenerator playerObj;

playerObj.playerHand1();

                }

There is a Code tag for a reason...

The warning is exactly as it sounds.  Your function playerHand1 doesn't return a value.

 

Consider

int myFunction() { //Error}vs.int myFunction2() {    return 1; //No error}

This throws the exact same error.  You notice how it is expecting to return an int, but myFunction doesn't return one.  The myFunction2 however does and will not throw an error.

 

If you don't want a value to be return your declaration should be

 

void playerHand1.....

I don't know how I missed that, thanks.
