In C++

Define a C-string function void copyWithFilter(char * destination, const char * source, const char * filter) that copies the characters of C-string source into destination, but omits any characters that are NOT in the C-string filter. For example filter(w, "bananas", "aeiou"); cout << w; will output "aaa". Hint: include a helper function bool isIn(char c, const char * s) ; that returns true iff c is a character in s. Use pointer notation. No square brackets allowed. Driver at http://www.chabotcollege.edu/Faculty/jtraugott/CodeLab/filter.cpp
