请问是怎么回事??以前很少用goto,所以想请高手指点.谢谢

[解决办法]
goto 是关键字, 不是函数
[解决办法]
使用gotoxy()

void gotoxy(int x, int y);

Description

Positions cursor in text window.

gotoxy moves the cursor to the given position in the current text window. If the coordinates are in any way invalid the call to gotoxy is ignored. An example of this is a call to gotoxy(40,30) when (35,25) is the bottom right position in the window. Neither argument to gotoxy can be zero.

Note:Do not use this function in Win32 GUI applications.

Return Value

None.
