Hello .I'm wondering if I can draw letter "O" inside and print it to the terminal (in Arduino I can do it with byte data type)
I don't know if I'm being understandable,but if so,how can I do it using C language?
Also, can I draw any shape I want (like circle,rectangle ,etc)?
Do you have any ideas or link of how can I do it?
Thanks!!

What I have tried:

I have tried nothing yet,because I have no idea how to do it

Yes, you can draw shapes, print letters etc. See GDI+ - Win32 apps | Microsoft Docs[^].

I forgot to say that I want to draw a shape without graphics.

Well that is a totally different question. You can draw a simple shape using existing characters:

H    H  +------+
H    H  |      |
HHHHHH  |      |
H    H  |      |
H    H  +------+

But I suspect that is not what you are asking.

no this is not what I want ,but thanks for your try.I want to draw and print letter "O" inside , to look like a ball (same size with letter "O").

You have two choices:
1. Draw a letter 'O' and then move it around the screen by redrawing lines in a console application. A very poor implementation.
2. Use GDI+ (or even the old C based GDI) and draw proper shapes in a Windows application.

No. You cannot "add character shapes" to terminal applications - there is no facility for that, you would have to use Graphics for this. Nor can you draw shapes directly.

Terminal / console apps are meant to be simple text based programs - they aren't intended for flashy display work at all!

On the Arduino you can, because you have direct access to the hardware - that's not generally the case in applications.
