How can I add and track files in git without tracking the directories they are in?

Question

As you can see from the picture, I have some files nested in some directories. For example in the '../../roadTrip/' directory I have a file called 'main.cpp'. I want to track ONLY this file and not the directories it is in, because that is the only file I want to push to my remote repo. I tried ignoring the directories the file was in, in the .gitignore file by using wildcards, but it ignores the file also. Is there any way I can achieve this effect without having to literally take out the file from the nested directories and then push it?

--UPDATE! Below is a screenshot of my github remote repo. It shows the whole directory, and when I open it, the file is inside. This means the file was successfully pushed, but I don't want that. I want the file to be pushed alone without the directories it is in.

Something along the lines of this:

That is not possible with Git. Your remote repository will have the same structure the your working tree of your local repository. Nothing you can do about that.
