Draw Rectangle in C graphics

  • Difficulty Level : Medium
  • Last Updated : 04 Oct, 2018

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);


Take a step-up from those "Hello World" programs. Learn to implement data structures like Heap, Stacks, Linked List and many more! Check out our Data Structures in C course to start learning today.
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);
    // closegraph function closes the graphics
    // mode and deallocates all memory allocated
    // by graphics system .
    return 0;
