Function which return sign on some position

[gol350]

Welcome everyone !
I'm new on this site.
I love write what I have planed on my own even if the same function already exist.
This time my aim is to write function which return sign on some position like in
title. Arguments of this function are x and y coordinates.
So question.
What I have to know to do this ?
I don't know about this topic anything.
Don't know from what I have to begin.
Should I use function from header "windows.h"
Is it possible to write this without "windows.h" , only with variable.
Please help me.

What do you mean by the 'sign' on some position? Do you mean the character written at some (x, y) coordinate on the console screen?

Yes .
Maybe there must be third argument like this sign.

Using just standard C++, I don't think that is possible. With an external library like some Windows console functions or curses you could probably do it. I wouldn't be able to tell you too much beyond this, though.
