/*
* Write a program which accepts exactly 3 command-line arguments (other than the 
  program's name in argvalue[0]), converts each to an integer value, and prints
  the maximum of the 3 values.
* Rewrite your solution to the previous task so that it now prints the maximum 
  of an arbitrary number of command-line arguments, perhaps 3, or 10, or 20....
