Program 1. Write a program to read series of names, one per line, from standard input and  write these names spelled in reverse order to the standard output using I/O  redirection and pipes. 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. _ Algorithm: Step 1: Start Step 2: Enter your choice 1. From standard I/O 2. From Files Step 3: Select the choice- 1: Using Standard file 2: Using Files             Case 1: [using standard I/O]                          Enter the number of names to be read                          Read the value of N                          a. Read one name at a time        ...
