How do you append corresponding lines in one file to corresponding lines of another file

Question

For example if I have file A:

s  
s  
s  
s  
s

And file B:

d  
d  
d  
d  
d

How do I make file C:

s d  
s d  
s d  
s d  
s d

I have been trying to use sed, awk, and xargs but to no success. I'm using bash on a mac.

Either

paste -d ' ' A B > C

or

pr -Tm -s' ' A B > C

You can remove the delimiter specifications (-d ' ' and -s' ' respectively) if you don't mind the default (tab) delimiters.

Will paste work for you?

paste A B > C

It is extremely fast.
