头文件graphics.h包含outtextxy()函数,该函数在屏幕上的指定点(x,y)上显示文本或字符串。

用法:

void outtextxy(int x, int y, char *string);

where, x, y are coordinates of

the point and, third argument contains

the address of string to be displayed.

例子:

Input:x = 200, y = 150,

string = "Hello Geek, Have a good day !"

Output:

Input:x = 150, y = 250,

string = "GeeksforGeeks is the best !"

Output:

下面是outtextxy()函数的实现:

// C Implementation for outtextxy()

#include

// driver code

int main()

{

// gm is Graphics mode which is

// a computer display mode that

// generates image using pixels.

// DETECT is a macro defined in

// "graphics.h" header file

int gd = DETECT, gm;

// initgraph initializes the

// graphics system by loading a

// graphics driver from disk

initgraph(&gd, &gm, "");

// outtextxy function

outtextxy(200, 150, "Hello Geek, Have a good day !");

getch();

// closegraph function closes the

// graphics mode and deallocates

// all memory allocated by

// graphics system .

closegraph();

return 0;

}

输出:
