c语言vs可视outtext,C语言 closegraph()用法及代码示例

头文件graphics.h包含closegraph()函数，该函数关闭图形模式，释放由图形系统分配的所有内存，并将屏幕恢复为调用initgraph之前的模式。

用法:

void closegraph();

以下是closegraph()在C中的实现。

// C Implementation for closegraph()

#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, "");

// outtext function displays

// text at current position.

outtext("Press any key to close"

" the graphics mode !!");

getch();

// closegraph function closes the

// graphics mode and deallocates

// all memory allocated by

// graphics system .

closegraph();

return 0;

}

输出：

注意：执行程序时，输出窗口如下所示。按任意键时，closegraph()将关闭图形模式。
