Program furthering learning using Classes, private, public, constructor, functions, integers, and strings

Question

In my c++ class, we have been tasked to keep building different aspects into this code. I am currently getting 2 errors and am stuck where I don't know what I am doing wrong. The program takes a private car or string for a name and a private integer to be input into the game checking for divisibility by 3, 5, and both 3 & 5. I am to use a get function and a put function within the class taking the input values and outputting them. I have essentially figured out the program but it will not compile and I am really unsure why. Here is my code:

#include <iostream>
#include <iomanip>
using namespace std;
using std::istream;

// declare the max size the username input can be
const int MAX = 14;

enum FIZZBUZZ { ABORT = 0, FIZZBUZZ, FIZZ, BUZZ };


class CFizzbuzz                              // Class definition at global scope
{
    // make sure our constructor, destructor, plus member functions are
    // all public and available from outside of the class.
public:

    CFizzbuzz() {}              // Default constructor definition
    ~CFizzbuzz() {}             // Default destructor definition


                                // function members that are public

                                // get the user's name and their value from the console and
                                // store those results into the member variables.
    void getFizzbuzz()
    {
        cout << "Please enter your name: " << endl;
        cin >> m_myName;

        cout << "Please enter your number for the FizzBuzz game: " << endl;
        cin >> m_myNum;
    }

    // return the user's number type entered
    int putFizzBuzz()
    {
        return m_myNum;
    }

    char* getName()
    {
        return m_myName;
    }

    // logic to check to see if the user's number is 0, fizz, buzz, or     fizzbuz
    int getRecord(int num)
    {
        if (num == 0)
        {
            return ABORT;
        }
        else if (num % 5 == 0 && num % 3 == 0)  // fizzbuzz number
        {
            return FIZZBUZZ;
        }
        else if (num % 5 == 0)  // buzz number
        {
            return BUZZ;
        }
        else if (num % 3 == 0)  // fizz number
        {
            return FIZZ;
        }
        else
            return num;
    }

    // private data members only available inside the class
private:
    int     m_myNum;
    char    m_myName[MAX];
};


int main()
{
    CFizzbuzz   myClass;


    cout << "Welcome to my Fizzbuzz game, you are to guess the location of a "
        << "number which if is divisible by 5 and 3 you will win with "
        << "the output of Fizzbuzz. " << endl;
    cout << "Please enter an integer value between 0 and 3 "
        << "representing the row location of the number for the game, "
        << "then press the Enter key: " << endl;

    for (;;)
    {
        myClass.getFizzbuzz();

        int num = myClass.putFizzBuzz();
        switch (myClass.getRecord(num))
        {
        case ABORT:
            cout << myClass.getName() << "\nThank you for playing\n";
            system("PAUSE");
            return 0;   // exit program

        case FIZZ:
            cout << "Sorry, " << myClass.getName() << ", number is a Fizz, please try again.\n";
            break;

        case BUZZ:
            cout << "Sorry, " << myClass.getName() << ", number is a Buzz,    please try again.\n";
            break;

        case FIZZBUZZ:
            cout << "You win you got FizzBuzz!!!" << endl;
            break;

        default:
            cout << "Sorry, " << myClass.getName() << ", number is a not a Fizz, Buzz, or Fizzbuzz\nPlease try again.\n";
            break;
        }
    }
}

These are errors I'm getting:

LNK2019, LNK1120

Answer 1

Based on the errors you mentioned in comments (Unresolved external symbol _WinMain@16) I'd say that you created a Win32 project (a GUI project) in Visual Studio but your code is meant to be a console application.

You need to change the type of your project from Win32 application to Console application by either re-recreating it or changing the Subsystem from Windows to Console in project settings. See the following link for more information on the latter:
