Question

Using OOP, write a C++ program that will read in a file of names. The file is called Names.txt and should be located in the current directory of your program. Read in and store the names into an array of 30 names. Sort the array using the selection sort or the bubblesort code found in your textbook. List the roster of students in ascending alphabetical order. Projects using global variables or all code is in main() will result in a grade submission of 0. List of names in Names.txt: Jackie Sam Bill Tom Mary Paul Zev Barb John Sharon Dana Dominic Steven Padro Katey Kathy Darius Angela Mimi Jesse Kenny Lynn Hector Brittany Jenn Joe Chloe Geena Sylvia Dean
