1) You could use string.insert()
2) Specifically 3 characters away from the end. To get to this position, you would want to do something like this:
myStr.length() - 3;So, let's add those two together, along with the
. that we want to add to the string:
myStr.insert((myStr.length() - 3), ".");note that this is C++Hope this helps
EDIT:teehee, you drew a boob:
