bar3d() function in C graphics

Last Updated : 30 Jan, 2018

The header file graphics.h contains bar3d() function which is used to draw a 2-dimensional, rectangular filled in bar . Coordinates of left top and right bottom corner of bar are required to draw the bar. Syntax :

 void bar3d(int left, int top, int right, int bottom, int depth, int topflag); where, 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, depth specifies the depth of bar in pixels, topflag determines whether a 3 dimensional top is put on the bar or not ( if it is non-zero then it is put otherwise not ).

Example :

 Input : left = 150, top = 250, right = 190, bottom = 350, depth = 20, topflag = 1 left = 220, top = 150, right = 260, bottom = 350, depth = 20, topflag = 0 left = 290, top = 200, right = 330, bottom = 350, depth = 20, topflag = 1 Output :

Below is the implementation of bar3d() function :

CPP

// C Implementation for bar3d() function #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;  // initgraph initializes the  // graphics system by loading a  // graphics driver from disk  initgraph(&gd, &gm, "");  // location of sides  int left, top, right, bottom;  // depth of the bar  int depth;  // top flag denotes top line.  int topflag;  // left, top, right, bottom,  // depth, topflag location's  bar3d(left = 150, top = 250,  right = 190, bottom = 350,  depth = 20, topflag = 1);  bar3d(left = 220, top = 150,  right = 260, bottom = 350,  depth = 20, topflag = 0);  bar3d(left = 290, top = 200,  right = 330, bottom = 350,  depth = 20, topflag = 1);  // y axis line  line(100, 50, 100, 350);  // x axis line  line(100, 350, 400, 350);  getch();  // closegraph function closes the  // graphics mode and deallocates  // all memory allocated by  // graphics system .  closegraph();  return 0; }
