Thread: Objects

I'm having a little trouble with syntax with my program and i need some help.
Can anyone show me the syntax for calling a function from a class with an object as its paramter and the syntax for the function name in the class? i'm somewhat new and very bad at the syntax on passing parameters.

Thanks,
Dyn4sty

i get this error

error C2664: 'Poly::addPoly' : cannot convert parameter 1 from 'Poly *' to 'Poly'

The same as any other function.
Function_name(arguments);

as its paramter and the syntax for the function name in the class?

That's a little unambiguous. Do you care to try to re-explain that?

That means the function expects an object of type Poly to be passed by value but you are trying to pass a pointer.
If you have an object, you may be trying to pass the address:

Code:

void foo(Poly p) { }
int main()
{
    Poly mypoly;
    foo(&mypoly); // Wrong
    foo(mypoly); // Right

    // Or you may have a pointer
    Poly* pMyPoly = &mypoly;
    foo(pMyPoly); // Wrong
    foo(*pMyPoly); // Right. Dereference first.
}

Hope that helps.
