1. [10pts] TRUE/FALSE questions.
   • TRUE/FALSE   When compiling multiple source code files, in the g++ command, you should include all .cpp files.
   • TRUE/FALSE   When compiling multiple source code files, in the g++ command, you should include all .h files.
   • TRUE/FALSE   All .h files should start with #pragma once.
   • TRUE/FALSE   All .cpp files should start with #pragma once.
   • TRUE/FALSE   Suppose you create a library point.h and point.cpp that implements struct point. Then point.cpp should include point.h.
2. [50pts] Look at hw.cpp from last lecture. Download Makefile. The program uses a point struct and a struct hhmmss. Break the program as follows:
   • point library
   • hhmmss library
   • datum library
   • The main program
   The files will be compiled with the following command:

   make hw
   

   Inspect Makefile and check how the above command works. Here are the sample runs.

   $ ./roach
   Enter a time: [01:00:20]
   This was before the first sighting at (6.67,0.03)
   
   $ ./roach
   Enter a time: [02:40:10]
   The roach was somewhere between (3.08,0.61) and (2.05,4.7)
   
   $ ./roach
   Enter a time: [04:00:00]
   This was after the last sighting at (2.24,5.43)
   

   Turn in

   Turn in all relevant h and cpp files as follows:

   ~/bin/submit -c=IC210 -p=hw29 *.h *.cpp
