I'm taking a class on C, so try not to roast me too much.
Anyways, I have a file i'm supposed to input into my program that looks like this.
and i'm supposed to grab all the data between the colons and spit it back out.
It works on my linux machine, but on mac it doesn't?
I'm pretty sure it's the way it reads the end of the line, but i'm not sure.
Someone please help. Explain like I'm 5.
what it outputs on linux

Works fine for me too using gcc v4.8.4.
Are you getting any errors when trying to run it on your Mac, or no?

I'm using clang.
Do different compilers have different output?
Never mind. I'm using Atom to write my code, and Atom adds an extra line to every file for some reason.
that extra line was throwing off my results.
