having trouble using classes

I have an assignment to write a program that allows you to input either arabic or mayan numbers and convert them to each other. we are supposed to use a class containing all of the functions and variables. lucky for me my teacher from my previous class neglected to teach us classes so I am sort of learning them as I go along. So far everything seemed to work ok until I tried to write the function that outputs the mayan number. I have the mayan number stored in a char array. In my output function it compiles with a warning and I get an error when I run the program. But when I cout the array in the same function as I inputted it everything works out just fine. Any information would be great, Thanks!

My class.

Code:

---

class MayanNumberType
{
public:
        int GetArabicNumber();
        void GetMayanNumber();
        void ConvertToArabic();
        void ConvertToMayan();
        void PrintArabicNumber();
        void PrintMayanNumber();
        char MayanNumber[50];
        int ArabicNumber;
};

---

This is my input function.

Code:

---

void MayanNumberType::GetMayanNumber()
{
        MayanNumberType x;
        cout << "Please enter the Mayan Number: ";
        cin.ignore();
        cin.getline(x.MayanNumber, 50);       
}

---

This is my Output function. I am just outputting the first value in the array until I get it working.

Code:

---

void MayanNumberType::PrintMayanNumber()
{
        MayanNumberType x;
        cout << x.MayanNumber[0];
}

---

Why print the Mayan Number from x, which should print out (but, alas, probably won't) as "completely uninitialized data" when you can just drop the x and print out the Mayan Number of the calling object?

The problem is that "MayanNumberType x" creates a new instance of the class. So you input the number into an instance of the class (which is destroyed when the function ends) and then you create another instance in Print and print out whatever is inside.
They're not the same instance! Two different objects! So you can never expect to get the right answer.

You want the class to refer to itself (its own instance). You can do this by using they keyword this. But this->myvar is the same as just myvar.
So read into x, then print x later.

And I should probably tell you that classes aren't meant for this sort of thing. A class is meant to be like an object, like a car. It doesn't ask questions. It merely follows your command (and takes care of everything that needs to be done to make it rolling).
