I am implementing code to program a hangman game in C++ for my CSP class. So far, I am working on the random string function as well as calling the body parts as void functions. I am attempting to compile what I have as of now to see how it runs, but I run into a problem. I declared some variables in a function, so how do I use them and their values in the main portion of the program? The code and errors are posted here. I am trying to call the values of choice and hint as determined in the getString function in the main portion of the program.
// Kevin Richard
// Hangman.cpp
// Basic Hangman console game
/*
Changelog:
-added char guess, and string lettersUsed.
-implemented help call.
-added void subfunctions for the body parts of the hanged man.
