use char[some_length] or char *.

Do not use any string classes.
Note that whenever you can implicitly use a string like "rotate left"
you can use a char * (char []). This is because "Rotate left" is
actually a constant pointer to the string "Rotate left" that's stuck
somewhere in your data segment. In other words, passing "Rotate left"
for a char * parameter is like passing 5  (or some constant) for an int
parameter.

Is that fairly clear?
