Change Text Size in Console?

[buran]

I am no longer asking for your answer, but @buran, in the future, please do not ask a series of exhausting questions, not helping the poster in any way, only to then refuse answering because you do not like the poster due to some petty reason. You might let down a new programmer.

In fact I am trying to prevent an obviously new programmer from making mistake by assuming they know better what user wants. As I said - if you want to control feel and look - make a GUI/web app. That's exactly what your example about the graphics of a video game is. Using a CLI/terminal - you accept what your user preferences are, although some small modifications like color are acceptable (e.g. using ANSI control sequences).
In your original post you say the output in console is too tiny. That is subjective - I (and probably huge part of the population) find the default settings just fine. However you come and assume it's too tiny for all, just because you "think/feel" so. Finally, you ask how to change the settings of external program - the terminal/shell app used by the user, assuming incorrectly there is only one possible app they can use (cmd, right?). Note these are not settings in your program, but settings in another one. However there are many terminal/shell alternatives and you cannot account for all of them.
So, again and I stop here - make a GUI/web app if you want certain feel/look, don't mess with user preferences.
