Hello, I’m Lakshmi. I’m interested in C++ programming & web development.

I am expert in C++ and C programming

and can also create various types of graphics programs.

There is a program that I want to share with you all that I have made myself by learning from internet :

HOW TO DRAW CIRCLE IN C PROGRAMMING LANGUAGE

Program to implement Circle Drawing Algorithm

int x,y,r,d,x1,y1;
public:

{
x=0;y=0;
cout<<"
"Enter The Co-Ordinates Of The Circle ":=";
cin>>x>>y;
cout<<"
"Enter The Radius Of The Circle ":=";
cin>>r;
}

void myCircle::showCircle()
{
char *s;
x1=0;y1=r;
d=3-2*r;
while(x1<=y1)
{
putpixel((x+x1+320),(y+y1+240),5);
putpixel((x-x1+320),(y+y1+240),5);

outtextxy(100,240,"-X");

a.showCircle();
// closegraph();
}

This is the program to draw circle in C.However if you want to do
something else then go to javatpoint.com.You can also
ask your program in www.webhostssss.weebly.com if you dont find it
in javatpoint or any other website.
