Quick look at "Accepts a pointer to a C-String" What does this mean???

TheDMinor (20)
I have made this program run, however in the book it says my functions should "accept a pointer to a c-string as its argument." Please help me if you can.

What is the title and author of your book?

starting out with C++ from control structures through objects, by tony gaddis

I would be hesitant about any book claiming to teach C++ that requires you to use c-style strings. I would recommend just using std::string as you have already done.

Thought so, thank you for helping. Also, LB would you care to run my program, and help me fix the problem where, if you enter a string with spaces it does not compile right.
LB (13399)
You could replace line 20 with std::getline(std::cin, str); to read an entire line of input instead of just the first word.

Thank you, I thought I had that, guess I overlooked it lol
