How to colorize cells in the C++ output console?

Question

C++ / C#

I am writing a lab. work.
I have similar pictures.

Is it possible to do something so that when outputting to the console there are not 0 and 1, but black squares instead of zeros, and white ones (or vice versa, not the point)?

Answer 1

pay attention to

characters in column D (rows B,C and F)

All encodings commonly used by Windows, Linux and Unix consoles have their counterparts.
and also look at the output to the console of colored inscriptions

Answer 2

If your console supports colors, you can display black characters on a black background and white characters on a white background, creating "squares".
You can see what characters there are except for numbers of letters.
Well, among other things, the text console works with symbols, not graphics. The display may depend on fonts that have nothing to do with your program
