Exercise 10: WAP to Draw Bar Graph. (In this program, we will use line, setfillstyle and bar functions to draw horizontal and vertical axis and bars on screen.)

void main() {
    int gd = DETECT, gm;
    initgraph(&gd, &gm, "c:\\Turboc3\\BGI");
    settextstyle(BOLD_FONT,HORIZ_DIR,2);
    outtextxy(275,0,"BAR GRAPH");
    setlinestyle(SOLID_LINE,0,2);
   
    /* Draw X and Y Axis */
