draw a circle

[Future Epic]

hello guys :)
simply the problem is that i wanna to draw a simple circle put when i use the function (initgraph "which i don't know it's use :D ") it just gives me this warning ( warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]) and when i run all i get is crashing :/ and this is the code :

 #include<graphics.h>

#include<conio.h>

void main()

{

int gd=DETECT,gm;

initgraph(&gd, &gm, "c:/tc/bgi ");

circle(330,180,100);

getch();

closegraph();

restorecrtmode();

}

Try

initgraph(&gd, &gm, "c:\\tc\\bgi "); // You need to use double slashes

[Future Epic]

TarikNeaj i tryed it and still the problem :(

[germanchocolate]

Try using a c style string from where you input "c:/tc/bgi."

Something like this:

char path[] = "c:/tc/bgi";

germanchocolate@ when i run the program is crashing as i said :(

[TarikNeaj]

Use Double Slashes. single slashes are called escape sequences.

char path[] = "c://tc//bgi";

Edit: Use int main not void main.

Tarik believe me it has nothing about the slashes :)

Is the variable "gm" supposed to not be initialized?

Edit: Just researched and found a lot of examples about this Turbo C++ library and all have not initalized it, so nevermind.

choclate@ i've already intialized it here int gd=DETECT,gm;

[TarikNeaj]

Try

const char* path = "c://tc//bgi";

initgraph(&gd, &gm, path);

You declared gm, but you didn't initialize it.

Either way, I'm not familiar with this Turbo C++ library, so the best I could do is link you to this earlier thread about someone using the library. Maybe it will help you with something you may have missed: http://www.cplusplus.com/forum/beginner/58846/

dear chocolate :)
i don't use Turbo but i don't know how to draw a circle and determine it's coord. but the noticed way that i found while searching .. if you know a way to draw a circle and simple i'd be so glade to tell me :)

[germanchocolate]

Which library are you using then?

[Future Epic]

i have never ever tried to draw a circle this is the first time and i need a help (i'm using codeblocks)

The reason that you're having errors is because there is no default graphics library that you can include(that I'm aware of), so you're calling non-existent functions.

no no i have downloaded the graphics.h library and it works .. if u know a way draw a circle tell me

[TarikNeaj]

You can use the library SFML. You can draw a circle there in 2 lines of code.

sf::CircleShape shape(50);
shape.setFillColor(sf::Color(100, 250, 50));
