How do you intialize graphic mode in c?
Platform-dependent. For Turbo C, enter initgraph and press Ctrl+F1.
Why you are writing DETECT in computer graphics program?
because initgraph() automatically detect current available graphmode and load it on to the graphdriver.
Why in c language initgraph doesn't work?
Initgraph initializes the graphics system by loading a graphics driver from disk (or validating a registered driver) then putting the system into graphics mode.Initgraph also resets all graphics settings (color, palette, current position, viewport, etc.) to their defaults, then resets graphresult to 0.
How to use graphics in c plus plus?
At the beginning in the header file: #include <graphics.h>
Write a C Program to draw concentric circles using mid-point algorithm?

What is initgraph in computer graphics?
The initgraph() is a method that you always use when you want to write graphic programming in C++. It is used to initial graphi window before something can be drawn on the window.

What is bgi?
BGI stands for Borland Graphics Interface. These are the files that contains the information about the graphic functions to be used. These are responsible for performing graphic operations under dos. In Borland turbo c++ these files are contained in directory. -> c:\tc\bgi By default these are loaded in the current directory while compiling and executing the program under c/c++ but sometimes we need to specify their path in "initgraph() function. like: initgrapy(&gdriver,&gmode,"c:\\tc\\bgi"); otherwise it will display you error about bgi.
How do you draw a circle in c program?
Here, maybe a few other shapes as well#include#includevoid main(){int gd=DETECT, gm;int poly[12]={350,450, 350,410, 430,400, 350,350, 300,430, 350,450 };initgraph(&gd, &gm, "");circle(100,100,50);outtextxy(75,170, "Circle");rectangle(200,50,350,150);outtextxy(240, 170, "Rectangle");ellipse(500, 100,0,360, 100,50);outtextxy(480, 170, "Ellipse");line(100,250,540,250);outtextxy(300,260,"Line");sector(150, 400, 30, 300, 100,50);outtextxy(120, 460, "Sector");drawpoly(6, poly);outtextxy(340, 460, "Polygon");getch();closegraph();}
