Inlined functions as arguments

DarkAlex · 11-11-2009, 11:23 PM

I am attempting to inline a member function as an argument of an equation.

Code:

Player.hitper=((d10.roll-1)*10)+(d10.roll-1);

d10 is a object of the class dice.
The class to which the function belongs is as follows:

Code:

class dice
{
	public:
                       dice(int sides);
			int numsides;
			int roll()
			{
				(rand()%numsides)+1;
			}
};

The error I'm receiving is as follows:

Quote:

invalid use of member (did you forget the `&' ?)

I have tried to use the function with and without the 'return' keyword preceding the statement in the function.

What am I doing wrong here?

Did you #include <cstdlib> for rand()? Of course, it looks like you should have that statement as a return statement.

EDIT:
Oh, but this is wrong:

Code:

Player.hitper=((d10.roll-1)*10)+(d10.roll-1);

You are not calling the function. It should be:

Code:

Player.hitper=((d10.roll()-1)*10)+(d10.roll()-1);

Oh. That makes sense.

I guess I was thinking that I was using it as an argument.

Now that I'm calling the function correctly, the code complies.

Thanks for your help.
