OAC Problem Set III

Strings, Functions & Pointers Problem

For this problem, you are to use the functions which you wrote for Problem Set II: Length(), Pos(), Delete(), Insert() and Copy().

Include all of the following features in a single program.

The string "I love the Buffalo Bill legend." is stored in the variable CurrStr, which is local to main().
The user is allowed to change the string by insertion, deletion, replacement, upcasing.
The user is allowed to get the following information printed out: length of the whole string, location of a sub-string.
A one-line menu is presented to the user each time after the CurrStr is printed.
Bulletproofing.

Your program will have the following structure. You are to turn in a completed hierarchical structure diagram for your program. Include parameter information in your diagram.

                          main
                            |
