Project: Robot Logging Suite

Write a "robot logger" program which can log actions to a file, and also read actions from a file and perform them.

• You should use command-line input flags to specify whether the robot is in "read" mode (reading actions from a file) or "write" mode (logging actions onto a file). In particular:

  • if the use specifies a command-line directive -w, then

    • if the command line also has a file name, subsequent processing should use this file for writing. However, if no file name is given, the program should ask the user for a file name.
    • the program should read commands from the keyboard,
    • the program should perform the commands, and
    • the program log the commands in the specified file.

  • if the use specifies a command-line directive -r, then

    • if the command line also has a file name, subsequent processing should use this file for reading. However, if no file name is given, the program should ask the user for a file name.
    • the program should read commands from the specified file, and
    • the program should perform the commands.

  • if no command-line arguments are given, the program should remind the user that the program requires -w or -r.

• This program should support at least 10 different actions (following the module 3 project command requirements).

• You are encouraged to use either your module 3 project or your command-robot.c program as the basis for the command input.

Grading

This project will be worth 25 points, based on the following rubric:

• The program can write actions to a file. (5 points)

• The program can read back the actions file and perform those actions in order as listed in the file. (5 points)

• The program can be executed with the -w (write) flag and the -r (read) flag. (5 points)

• There are at least 10 different robot actions supported, with either standard i/o or command-line input supported (5 points)

• Code is well documented, reasonably efficient and well-structured, and example command files are given. (5 points)
