Write a program to ask the user his or her name. Read the response. Confirm that the input is at least two characters in length. If the name seems valid, respond to the user. Provide two implementations: one using a C-style character string, and the other using a string class object.

The two primary differences between a string class object and a C-style character string are that (1) the string class object grows dynamically to accommodate its character string, whereas the C-style character string must be given a fixed size that is (hopefully) large enough to contain the assigned string, and (2) the C-style character string does not know its size. To determine the size of the C-style character string, we must iterate across its ...
