Start with an array of pointers to strings representing the days of the week, as found in

the PTRTOSTR program in this chapter. Provide functions to sort the strings into alphabetical

order, using variations of the bsort() and order() functions from the PTRSORT program

in this chapter. Sort the pointers to the strings, not the actual strings.

– Write a C++ program that asks the user to input an integer n followed by n other decimals representing the ages of some people. These ages will be stored in a stack. The program will then read this stack and do the followings: if the age read is greater or equal to 20 then the program will insert in a queue the word OLD, otherwise it will insert in this queue the word YOUNG. The program will finally display on the screen the content of the stack and the queue.
