Thread: Constructor call difference

Hi

I have that test class

Code:

#include<iostream>

class TestClass
{
public:
	TestClass()
	{
		std::cout << "Constructor" <<std::endl;
	}


	~TestClass()
	{
		std::cout << "Deconstructor" << std::endl;
	}
};


int main()
{

	//what is the difference between them 
	TestClass rt; // show constructor, deconstructor output
	TestClass rt1(); // does nothing

	return 1;
}

I am interested what is the difference between the two object declaration, because second declaration ( TestClass rt1(); ) seems to do nothing


Thanks

TestClass rt1(); // does nothing

Because the compiler thinks this is a function declaration

rt1() is a function that takes no parameters and returns a TestClass.

Incidentally, the more usual word for what you're calling "deconstructor" is "destructor".
