Lab 13 Study

Lab 13 Be sure to put each class in its own file. The referenced pages contain four short programs that demonstrate string functions. Combine logic from these programs to create your own big program that demonstrates these string functions. Put all this in a loop. Accept one or more strings from the user and use these strings in the string functions in your program.
