Thread: One more enum question

I am creating an ADT named RowstackException which inside the class, It should contain a public enumerated typed named RowstackExceptions. There will only be one value in the enumerated type: RowStackEmpty

Since I don't use enum always, I don't have idea how to code for this, can anyone gives me some suggest.
Here is what i code

Code:

enum RowStackExceptions;

Does it like that?

what is that for the second link?

Coz i am gonna to throw an exception when the stack doesn't have card

So, for the code, Can I use that?

Code:

enum RowstackExceptions { RowstackEmpty };

In C++, you can create your own types with the 'class' keyword or the 'enum' keyword. Using the 'class' keyword, the following creates a type Card:

Code:

#include <iostream>
using namespace std;

class Card
{

private:
	int x;
	double y;

public:
	Card()
	{
		x=10;
		y=25.5;
	}

	void display()
	{
		cout<<x<<endl
			<<y<<endl;
	}
	
};


int main()
{
        Card c;  //declare a variable of type card
	c.display();
	
	return 0;
}

Using the 'enum' keyword, the following creates a type MyException:

Code:

#include <iostream>
using namespace std;

enum MyException
{
	exception1,
	exception2,
	exception3
};

int main()
{
        MyException exc;   //create a variable of type MyException
	exc = exception3;  //assign the variable one of the three allowed values
	cout<<exc<<endl;   //shows that the allowed values are actually equivalent to int values
	
	return 0;
}

By the way, you asked this same enum question before, and it was explained to you then why that statement is wrong.
