[help] style of object creation in C++

[halagi]

Hello,
I met a statement like the following. But I don't know whether the statement of object creation is ok.

1 2 3 4 5 6

class Fraction{ private: ......... public: Fraction(){} };

int main(){ Fraction a();//I don't know this statement is ok return 0; }

I don't know this statement is ok

It defines a function [prototype] a that returns an object of type Fraction with no parameter.

This is something that often confuses people. Fraction a(); looks as though it ought to create an object using the default constructor, but it doesn't. In fact, as coder777 says, it declares a function.

To create an object using the default constructor, just do:

Fraction a;
