Windows.h: COORD function error

I have use a function of <windows.h> library. And I have met error with MS Visual Studio 2010, but when I compiled on Dev-C++, No problem. Here my code:

Code:

void gotoXY(int x, int y)
{
	COORD coor;
	coor.X=x;
	coor.Y=y;
	int a =coor.X;
	SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),coor);
}
void clearLine(int line)
{
	COORD coor;
	int x=coor.X;
	int y=coor.Y;   //Error in this line: VS 2010 . but no problem in Dev-C++
	gotoXY(0,line);
	for(int i=0;i<50;i++) std::cout<<" ";
	gotoXY(x,y);	//back to the past cursor
}
int main ()
{
	 gotoXY(3,4);
	 clearLine(0);
	 getch();
   return 0;

}

when I compile, VS tak error:

the vaialbe 'coor' is being used without being initalized

who know this problem, tell to me,please.
thanks

In the following snippet:

Code:

void clearLine(int line)
{
    COORD coor;
    int x=coor.X;
    int y=coor.Y;   //Error in this line: VS 2010 . but no problem in Dev-C++
    gotoXY(0,line);
    for(int i=0;i<50;i++) std::cout<<" ";
    gotoXY(x,y);    //back to the past cursor
}
}

Where does the value coor.X and coor.Y come from? Before you can use these values in a equation they must be assigned a value.

Also if you turn on the warnings with Dev-C++ it would also produce some warnings.

Oh, thanks very much. May I have understand. if I don't thinking wrong, coor.X and coor.Y are just parameter of struct COORD. (but before that, I think coor.X and coor.Y is the present cursor) so I get the present cursor and save it.
So, how can I take the current cursor, can you teach me ?
thanks

Search the web for how to use the GetConsoleScreenBufferInfo function for that purpose.
