El archivo de encabezado graphics.h contiene la función bar() que se usa para dibujar una barra rellena rectangular bidimensional.
Sintaxis:
void bar(int left, int top, int right, int bottom); 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.
Ejemplos:
Input : left = 150, top = 150,
right = 190, bottom = 350
left = 220, top = 250,
right = 260, bottom = 350
left = 290, top = 200,
right = 330, bottom = 350
Output :
Input : left = 150, top = 250,
right = 190, bottom = 350
left = 220, top = 150,
right = 260, bottom = 350
left = 290, top = 200,
right = 330, bottom = 350
Output :
A continuación se muestra la implementación de la función bar().
// C implementation of bar() 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;
// left, top, right, bottom denotes
// location of rectangular bar
bar(left = 150, top = 150,
right = 190, bottom = 350);
bar(left = 220, top = 250,
right = 260, bottom = 350);
bar(left = 290, top = 200,
right = 330, bottom = 350);
// 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;
}
