Write a C++ code based this question n this assignment you will create three additional functions for each one of the data structures created in class. You will be provided with a header file which you will modify and a demo program for each data structure. If your functions are implemented correctly the demo programs should compile and execute correctly. Part 0 (Comments) 1. Over the course of the semester we have discussed comments for each data structure. Please add...
