C程序如何把窗口的光标定位到x,y坐标？

[chen327684096]

RT，想把键盘中输入的数据从x,y坐标开始显示，有什么函数可以办到？

[失散糖]

WinTC下,gotoxy函数可以

[chen327684096]

VC下不可以吗？那当我用scanf函数的时候，如何把键盘里面输入的数据从x,y处开始显示，而不是光标闪烁的地方？

C编译器下 moveto()

moveto要如何用？

[坏男孩]

//Linux 下的光标定位
void inline setPosition(int x,int y)
{
 char strp[20];
 sprintf(strp,"\033[%d,%dH",x,y);
 cout << strp;
}

 

//windows 光标下位
void gotoxy(int x,int y)
{
 COORD c;
 c.X=x-1;
 c.Y=y-1;
     SetConsoleCursorPosition   (GetStdHandle(STD_OUTPUT_HANDLE),   c);  
}

好复杂啊，一个光标定位需要用这么多语句吗？

moveto　　
功 能: 将CP移到(x, y) 　　
用 法: void far moveto(int x, int y); 　
CDC::MoveTo（int x,int y) 　　
Cpoint MoveTo(int x,int y) 　　
Cpoint MoveTo(POINT point) 　　
x：新位置的横坐标 　　
y：新位置的纵坐标 　　
point：标识的一个新的位置，以POINT 结构或CPoint 类对象的形式表示。 　　
程序例: 　　

#include <graphics.h> 　　
#include <stdlib.h> 　　
#include <stdio.h> 　　
#include <conio.h> 　　

int main(void) 　　
{ 　　
/* request auto detection */ 　　
int gdriver = DETECT, gmode, errorcode; 　　
char msg[80]; 　　
/* initialize graphics and local variables */ 　　
initgraph(&gdriver, &gmode, ""); 　　
/* read result of initialization */ 　　
errorcode = graphresult(); 　　
if (errorcode != grOk) /* an error occurred */ 　　
{ 　　
printf("Graphics error: %s\n", grapherrormsg(errorcode)); 　　
printf("Press any key to halt:"); 　　
getch(); 　　
exit(1); /* terminate with an error code */ 　　
} 　　

/* move the C.P. to location (20, 30) */ 　　
moveto(20, 30); 　　
/* plot a pixel at the C.P. */ 　　
putpixel(getx(), gety(), getmaxcolor()); 　　
/* create and output a message at (20, 30) */ 　　
sprintf(msg, " (%d, %d)", getx(), gety()); 　　
outtextxy(20, 30, msg); 　　

/* move to (100, 100) */ 　　
moveto(100, 100); 　　
/* plot a pixel at the C.P. */ 　　
putpixel(getx(), gety(), getmaxcolor()); 　　
/* create and output a message at C.P. */ 　　
sprintf(msg, " (%d, %d)", getx(), gety()); 　　
outtext(msg); 　　
/* clean up */ 　　
getch(); 　
closegraph(); 　　
return 0; 　　
}

这种控制台的输出建议还是不要深入研究的好，费力而无用，

可以直接学习WINDOWS框架下的图形输出接口，现在多数开发

语言都有封装好的接口，非常简单。
