Why are these codes doing this?

[CodeNovice01]

Here are two different codes with the same information just about. But each code is different. Each time I run one the output is vertical, when I run the other the output is horizontal. I'm too new at this to understand why. Can someone pinpoint the issue? Also, how would I include a comma for each array number in the output?

Horizontal code.

13 and fourteen puts then endl on the same line as the file output.
I am not entirely sure but maybe in the first code since it is on a second line it is only done once. I suggest you put brackets in your code to reduce ambiguity and maybe more things like that will show up.

I figured it out. I needed to remove an endl; in the code which prevented the numbers to align horizontal. Sorry for wasting your time if you've read this.

Just do us a favor and mark this thread as answered and yer good lol 😆
