Q about operator overloading and default constructors

[Dazzer]

Could someone please tell me why the code below doesn't compile?

I'm specifically interested to know why the call at line 22 to initialize with a default constructor breaks it!

class MyClass
{
private:
	int m_x;
	public:
	MyClass(int init) { m_x = init; }
	MyClass()
	{
		m_x = 7;
	}
	friend MyClass operator+ (MyClass &Class1, MyClass &Class2);
	int getm() { return m_x; }
};

MyClass operator+ (MyClass &Class1, MyClass &Class2)
{
	return MyClass (Class1.m_x + Class2.m_x);
}

int main()
{
	MyClass ClassA();
	MyClass ClassB(101);
	MyClass AddClass(ClassA + ClassB);
	std::cout << AddClass.getm() << "\n";
}

Line 22:ClassA is interpreted as a function that returns MyClass. Just remove the () after ClassA.

Oops, silly mistake, thanks!
