Drawing shapes (in C)

[Mo5]

Can anyone point me to a good site where it shows you (the code) how do you do it... It's a classic problem, but I haven't been able to find anything useful.

Any help is appreciated

Do you plan to draw in the command line (ex: ASCII art) or are you using some kind of graphics library?

Exactly my question as well^.

 

Anyway,here is a very good playlist(not yet completed) of 3D Software Rendering,explaining lots of stuff.You'll learn a lot about how rendering really works. On the other hand, it is in Java,so you can't really use it too much.It's good for understanding rendering as a whole.

OpenGL can be used with C

[Mo5]

Exactly.

Actually it's just the simple drawing (printf) with *. Nothing to fancy. Things like this:

****

*  *

*  *

(imagine that is a hollow square).

Need it for school BTW.

Do you have to use C? If you want to do graphics I'd recommend using Java it's much easier.

Oh....

Does it need to have any user input?Like draw a triangle for "triangle" input or something?

[mopman94]

Oh I see ASCII, yeah. You're probably going to have to hard code that.

[Mo5]

No. Unless the size counts.

[mopman94]

No. Unless the size counts.

Explain the problem you are trying to solve fully and I will give you a few hints. Don't expect anyone to do it for you though as it is homework.

[Nineshadow]

No. Unless the size counts.

So you want to draw stuff like these?

just print'em.What's so hard?

I don't know how it's in c,but in c++  : cout <<"****" << endl << "*  *" << endl << "*  *" << endl << "****";  (for a square)

Just print each line then go ahead and print a new line.

 

But what exactly are you trying to do???

[Mo5]

Well it's not homework, but we did do a couple of examples in school so I do know a basic concept (2 for loops, and a bunch of ifs) but I didn't fully understand it.

yup, exactly things like those

[mopman94]

I'm not sure what else you need to know to solve this problem?

the trick is you need to do it so you can easily expand it (user definable size). So you need to put it in a for loop. And then of course you need some ifs and there's where it stops for me. It's those ifs that get me.

It's really simple, think about it.

On the n-th line you need to draw n chars.
