   The correct value is  7 .  This is not the actual

   number that each command in the UNIX pipe receives!

   Assume that a command line is: 

    list  file_1  file_2  file_3 

   and the source file for the program

   list contained the statement:

   if ((fps = fopen(*argv++, "r"))) {

   Please type in the name of the first file

   that will be opened!

 Sorry, try again.

 No, try one more time.

   The correct answer is list, which is probably not the 

   desired file.  This problem in the code may be corrected 

   by using pre-incrementing on argv.
