GetLongLong() exists for a good reason. I distinctly remember not liking atoi and cin >> var, having to deal with whitespace/newline characters getting left on stdin, trying to peek/putback values, buffer the characters into a fixed-length array when I started programming. Even though this problem could be solved with string manipulation, you have to remember how limiting your toolset was when you first started out programming.

But the cs50.h library is meant to be a helper library for the first few weeks, so I guess I should try your method. Regarding the second assumption, do you ever check for the length of the inputted number? If yes, would you do it before or after the switch statement? | |
