Creating a class

So I'm new to this whole class thing. My prof gave me a main function and asked us to derive class defenitions and stuff. Main is as follows:

Code:

int main( void ) //do not change or modify this function
{
	DynamicFraction frA; //line 1
	frA.print();

	DynamicFraction frB( 4 ); //line 3
	frB.print();

	DynamicFraction frC( 3, -4); //line 5
	frC.print();

	DynamicFraction frD( frB ); //line 7
	frD.print(); //line 8

	frA = frB + frC; //line 9
	frA.print(); //line 10

	frA = frB - frD; //line 11
	frA.print();

	frB.print();
	frC.print();
	frD.print();

	if ( frA > frC ) //line 16
	{
		cout << "frA is greater than frC" <<endl;
	}
	else if ( frA == frC ) //line 17
	{
		cout << "frA is equal to frC" << endl;
	}
	else
	{
		cout << "frA is less than frC" << endl;
	}

	cout << endl; //line 38
	return 0; //line 39
}

I tried my best to create a class that satisfies all that but I keep getting loads and loads of errors. Help/tip/etc would be much appreciated

post the code you have for the class so we can comment on where you have missed the mark.

All we have is this:

Code:

class DynamicFraction
{
public:
//Filling in Constructors and Destructors; Proper getters and setters; Required utilities and operator functions

private:
int* ptrNum;
int* ptrDenom;
};

Not helpful, I know. But that's all I have and we're expected to fill it in =(
I don't even know how to get started. Pathetic, really.

Based on:

DynamicFraction frB( 4 );

DynamicFraction frC( 3, -4);

You have two constructors, besides the default constructor, right?
So start there.

You're just supposed to fill in the missing parts in the class, right?
This one's a toughie, since it uses constructors, a function and operator overloading.
There. You can try to read a little on those three things and see how well you can do it.
Then check back if you run into trouble.
