Rewrite the Demetris Leadership Center (DLC) program (a. k.a Program 8-3) so that two changes are made: • A Linear search is done, rather than a binary search. • Vectors are used instead of arrays. • Both Programs 8-3, which uses the binary search and 8-1, which uses a linear search, have been included so you can see what changes need to be made. • When you have the modified Program 8-3 working, call the instructor over so you may demonstrate your program.
