Objective

To gain experience in the use of pointers and pure pointer notation.

Assignment

Modify lab $4$B by replacing all array notations with pure pointer notations. However, arrays must still be defined. No subscripts in functions.

Run

The program multiple times with different user entered string and replacement characters showing all test cases and scenarios including invalid strings.

Turn In

Turn in source code and output file.
