Why use typedef struct instead of simply struct

[Dark Byte]

Hi, I can not see the difference in:

typedef struct
{
	float x,y;
} Vector;

typedef struct Vector
{
	float x,y;
} ;

And

struct Vector
{
	float x, y;
} ;

Is there a reason to use one over another? They all seem to do precisely the same thing.

The first is often used in C so that you can refer to the struct without having to prefix the name with "struct". I don't think the second is legal. The third is used when you don't care about/mind putting "struct" in front of the name of the structure or in C++, where it automatically makes a typedef for you.

+1 Zhuge.

The typedef thing is a weird C thing. You don't have to do it in C++.
