Here is a C program to draw a rectangle and a bar on screen using graphics.h header file. In this program, we will draw a rectangle and a bar on screen. We will use rectangle and bar functions of graphics.h header file to draw rectangle and bar on screen. Below is the detailed descriptions if these two functions.
| Function | Description |
|---|---|
| initgraph | initgraph is a fundamental function in Turbo C graphics that initializes the graphics system. It sets up the graphics mode, graphics driver, and the location of the BGI (Borland Graphics Interface) driver file. This function must be called before any graphics operation is performed. |
| rectangle | The rectangle function is used to draw a rectangle on the screen. It takes two pairs of coordinates, representing the diagonally opposite corners of the rectangle, and draws the outline of the rectangle. |
| bar | The bar function is used to draw a filled rectangle (bar) on the screen. It takes two pairs of coordinates, representing the diagonally opposite corners of the filled rectangle, and fills the interior with the current drawing color. |
| closegraph | closegraph terminates the graphics mode and deallocates any system resources that were acquired during the initialization of the graphics system. It should be called before exiting a graphics program. |
These functions collectively provide essential capabilities for drawing and manipulating graphical elements in Turbo C. Understanding and effectively utilizing them empower programmers to create diverse visual elements and designs in their graphics applications.
C program to draw rectangle and bar using graphics
#include<stdio.h>
#include<graphics.h>
int main(){
int gd = DETECT,gm;
initgraph(&gd, &gm, "C:\\TC\\BGI");
/* Draw rectangle on screen */
rectangle(150, 50, 400, 150);
/* Draw Bar on screen */
bar(150, 200, 400, 350);
closegraph();
return 0;
}
