/*
 * Assignment Two
 *
 * Write a C program that accepts up to 255 arguments and
 * displays these arguments individually, one per line.
 * Now have the program run a new program specified on the
 * command line.  Use "man execl" to see the description
 * of the system service "exec."  Be sure to specify the
 * complete path (/bin/ls) to run the desired program.
 *
 * DO NOT HAND IN THE EXAMPLE PROGRAM.  You must submit
 * a working derivative of the example program.
 * 
 * For more information on other forms of the exec()
 * service, use the Unix "man" command and read about exec
 * in section 3 with the command "man 3 exec"
 *
 * Use the script program to show the program source code,
 * its compilation, and run time behavior.  Show success
 * and failure of executing the command argument.
