// LAB PROGRAM 1. Write a C++ program to open a series of names 1 per line, from standard input and write these names in reverse order to the standard output using I/O redirection and pipes.
//Part b: Repeat the exercise using an input file specified by the user instead of the standard input and using an output file specified by the user instead of the standard output.
