tmp._c = _c+b._c;
return tmp;
}
};
template
class A {
T_v;
public:
A() {}
A(T v): _v(v){}
T getV() { return _v; }
void add(T & a) { _v+=a; }

Definitely a runtime exception, I can feel it!

I thought it would run fine, what's the issue?

Wait, why wouldn't it compile?

Looks like a compilation error to me.

I practiced a similar question where a class was not properly defined, and it didn't compile. I wonder if this is the same case.

The `add` function takes a reference, but I feel like it might be missing a proper operator for `C`. Could that be why it fails?

I remember something about operator overloading, but I'm not sure if it applies here since `C` is being used in a template class.

I think the code won't compile because of the way the `add` function is trying to use the `C` class.

Ah, I think I've got it! The key is checking the Allow Inline Editing for Inventory Items preference. That's likely the culprit here.

Hmm, this looks like a tricky one. I'd probably start by adding a System.debug() statement before the insert method to see what's going on.
