Answer to Question #6646 in C++ for Mathew Alvarez

Question

I need to modify the class CodeVisitor to accept a command line option -k to specify a keyword so it displays the names and sizes of all the files, whose names contain the given keyword in a given directory or directories. CodeVisitor currently uses the following command line options: -r, -d, -f and they should remain as they are now.
