Is there any way to assign properties to differentiate values which would otherwise be considered the same? (in C language)

Let me start by saying that I'm a beginner programmer that knows very basic C The exact code I'm working on doesn't matter here its just that I've run into a very odd problem (I'm messing around with ASCII graphics)

I want to differentiate between two 'O' characters. I could just use different characters but I want it to look good. I tried using Unicode to differentiate them (since Latin O and Greek Omicron look the same) but it won't work if I send it to someone else (since my output is on command prompt) edit: won't work if I send it to someone since command prompt must be manually configured to allow unicode characters (atleast to my understanding)

I don't know if using structures would work and I want to write this in C and not any other OOP language like python (because I'm practicing C)

So is there any logic I could use to do this?

EDIT: I want to apply different behaviours to both O and there will be multiple O of each type on screen (ik this is what objects do but pls help me with a logic for C)

EDIT 2: Apparently my question is very vague so I'll elaborate

I'm having a 2d array that I'm using as a game screen I want O to come in from each side (top bottom right left), scroll across the screen and exit from the other side

I already came up with the logic to make it work for a single side but the problem comes in when I want to make it work for all sides

My current logic can't differentiate between an O that has to go left and and O that has to go down

Hence why I want to different between two instances of O

(I haven't posted my code since I just need the logic and want to solve the actual code by myself and also it's probably very inefficient or convuluted etc)

tldr: I want to differentiate between "O" and "O"

Solution

  • My current logic can't differentiate between an O that has to go left and and O that has to go down

    Your problem is that you don't differentiate internal representation and external presentation.

    You have two distinct objects that move across the screen. They both look like an O character. This doesn't mean your program should store them both as 'O', some variation of 'O' such as the omicron character. The program can store e.g. numbers 1 and 2, or any two different objects that are convenient to work with, and display an O in place of either.
