The purpose of this assignment is to familiarize you with the notion of encapsulation as well as some aspects of IP and ICMP.

Write your programs in C or C++. They will be graded on the Computer Science Department's Linux facility, linux-lab.cs.stevens.edu. Submit your source code, a Make?le, and a README ?le via WebCT. These should be the only ?les submitted-do not submit any derived ?les or "garbage" ?les. Typing nothing more than "make" should create all executables. Write your Make?le to set the values of CXX and CXXFLAGS1(preferred), or include a README ?le that explains how to set the corresponding environment variables in the shell. You should set CXXFLAGS or CFLAGS to include the highest level of error checking: "-W -Wall -pedantic-errors." Ensure that your code compiles without warnings using these options.

The README ?le should explain how to start and use your programs, what features you do/don't have working, and any other information that will help the grader to determine the maximum grade that you deserve. Note that WebCT's clock and your clock may differ by a few minutes, so please submit several minutes before the deadline.
