getbkcolor() function in C

Last Updated : 23 Jan, 2018

The header file graphics.h contains getbkcolor() function which returns the current background color. Syntax :

int getbkcolor();

As getbkcolor() returns an integer value corresponding to the background color, so below is the table for Color values. Colors Table :

COLOR               INT VALUES
-------------------------------
BLACK                   0
BLUE                    1
GREEN                   2
CYAN                    3   
RED                     4
MAGENTA                 5
BROWN                   6 
LIGHTGRAY               7 
DARKGRAY                8
LIGHTBLUE               9
LIGHTGREEN             10
LIGHTCYAN              11
LIGHTRED               12
LIGHTMAGENTA           13
YELLOW                 14
WHITE                  15

When the background color is black:

// C Implementation for getbkcolor function
#include <graphics.h>
#include <stdio.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;
    char arr[100];

    // initgraph initializes the
    // graphics system by loading a
    // graphics driver from disk
    initgraph(&gd, &gm, "");

    // sprintf stands for “String print”.
    // Instead of printing on console, it
    // store output on char buffer which
    // are specified in sprintf
    sprintf(arr, "Current background color = %d",
                                 getbkcolor());

    // outtext function displays text
    // at current position.
    outtextxy(10, 10, arr);

    getch();

    // closegraph function closes the
    // graphics mode and deallocates
    // all memory allocated by
    // graphics system .
    closegraph();

    return 0;
}

Output :

When the background color is other than black:

// C Implementation for getbkcolor function
#include <graphics.h>
#include <stdio.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;
    char arr[100];

    // initgraph initializes the
    // graphics system by loading a
    // graphics driver from disk
    initgraph(&gd, &gm, "");

    // set background color as RED
    setbkcolor(RED);

    // sprintf stands for “String print”.
    // Instead of printing on console, it
    // store output on char buffer which
    // are specified in sprintf
    sprintf(arr, "Current background color = %d", 
                                 getbkcolor());

    // outtext function displays text
    // at current position.
    outtextxy(10, 10, arr);

    getch();

    // closegraph function closes the
    // graphics mode and deallocates
    // all memory allocated by
    // graphics system .
    closegraph();

    return 0;
}
