Draw Rectangle in C graphics
rectangle() is used to draw a rectangle. Coordinates of left top and right bottom corner are required to draw the rectangle. left specifies the X-coordinate of top left corner, top specifies the Y-coordinate of top left corner, right specifies the X-coordinate of right bottom corner, bottom specifies the Y-coordinate of right bottom corner.
Syntax :
rectangle(int left, int top, int right, int bottom);
Examples:
Input : left = 150, top = 250, right = 450, bottom = 350; Output : Input : left = 150, top = 150, right = 450, bottom = 450; Output :
Below is the implementation of the rectangle function :
// 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 int gd = DETECT, gm; // location of left, top, right, bottom int left = 150, top = 150; int right = 450, bottom = 450; // initgraph initializes the graphics system // by loading a graphics driver from disk initgraph(&gd, &gm, "" ); // rectangle function rectangle(left, top, right, bottom); getch(); // closegraph function closes the graphics // mode and deallocates all memory allocated // by graphics system . closegraph(); return 0; } |
Output:
