在C图形中绘制矩形-yiteyi-C++库

矩形（） 用于绘制矩形。绘制矩形需要左上角和右下角的坐标。left指定左上角的X坐标，top指定左上角的Y坐标，right指定右下角的X坐标，bottom指定右下角的Y坐标。 语法：

null

rectangle(int left, int top, int right, int bottom);

例如：

Input : left = 150, top = 250, right = 450, bottom = 350;
Output : 


Input : left = 150, top = 150, right = 450, bottom = 450;
Output :

下面是矩形函数的实现：

                     // C program to draw a rectangle                   
                     #include <graphics.h>                   
                             
                     // 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

                                         rectangle(left, top, right, bottom);                   
                             
                                         getch();
