As discussed in class several times, you should use the built-in
"string" type for storing and managing strings. By default, such
strings hold up to 255 characters. You can index into them just
like arrays. Also, as discussed in class, the input lines fed to
your program (the input expressions) will never exceed the length
of the built-in string type.
