请问大家这个gotoxy函数没有用？
程序如下：

C/C++ code

#include <stdio.h>#include <stdlib.h>#include <windows.h>void gotoxy(int x,int y){    COORD C;    C.X = x;    C.Y = y;    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),C);}int main(){    printf("Hello world!\n");    gotoxy(300,400);    printf("Hello world!\n");    system("pause");    return 0;}

[解决办法]
int main()
{
printf("Hello world!\n");

gotoxy(10,20);
printf("Hello world!\n");

system("pause");
return 0;
}
MSDN:The coordinates must be within the boundaries of the console screen buffer.
按照原先的300，400，检测SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),C)返回值为0；
