Classes

Hi there,

I have a class within a class. How do I create an object of the sub class and then use it.

eg)

Code:

class setA
{
protected:	
	int Weight;
	string Name;

	void SetWeight(int Weight_in) { Weight = Weight_in; }
	void SetName(string Name_in) { Name = Name_in; }

public:
	class part1
	{
	protected:
		int DescentRate;
		double MaxHeight;

		void SetDescentRate(int DescentRate_in) { DescentRate = DescentRate_in; }
		void SetMaxHeight(double MaxHeight_in) { MaxHeight = MaxHeight_in; }
	};
};

How could I access and hence use setdescentrate() in the main???

Thanks

With the scope resolution operator, "setA::part1" is the full type name.

Thanks for replying

I thought that but it didnt and still doesnt work

Code:

void main(void)
{

	SetA::part1  x;

	x.SetDescentRate(12);

	

}

Gives an error.

error C2248: 'SetA:art1::SetDescentRate' : cannot access protected member declared in class 'SetA:art1'

Can anyhone explain? any ideas? explanations?

Well, you can hardly expect to make something "protected" and then access it from a public context...

ha! sorry yeah

As the error clearly outlines, the problem was not with creating an instance of the class, but calling a protected member function of that instance.
You should learn to interpret error messages better.
