Circle code

[chump1708]

Can anyone give me an idea for drawing a circle without making use of
any floating point computations?
Thanks

Asking in comp.programmin g is possibly a better idea.

If you try to implement this in C, and have questions, you can always
come back here.

Sure. Take compass, insert pencil in pencil holder, place pointy
end on desired circle center, adjust compass for appropriate
radius, and spin it.

What was your question about the C language?

This is not a C language question.
Try asking in "comp.graphics. algorithms",
and/or search for "Bresenham’ s Algorithm"

Why? That seems a fairly useless thing to do.

Use a compass and a pencil.

I used no floating point calculations in
conceiving or presenting this idea.

come back here.

this C program draws one circle without any fp:

#include <stdio.h>
int main(int argc, char **argv) {
printf("o\n");
}

Solution #1:
------------

#include <stdio.h>

int main(void)
{
putchar('O');
}

Solution #2:
------------

#include <stdio.h>

int main(int i, char **v)
{
int c='\n',_=-c,y;
for(y=i-c;putc((_*_<c*c-y*y)?0x2a:040,s tdout),_<=c;++_ );
return((puts("" )&&c>y)?main(++ i,v):i^i);
}

This program is not correct C:

#include <stdio.h>
int main(int argc, char **argv) {
printf("o\n");
return 0;
}

Also I was not the OP.

Here's the LOGO / differential geometry solution:

repeat
go forward 1 unit
turn right 1 unit
