(1) Go over the Farenheit to Celsius program at:

   http://udel.edu/~pconrad/cisc181/05S/work/labs/lab01/lab01b.cc


(2) Compling on strauss

   ">" means the Unix prompt
 
   Show how to compile this with just 
        > CC lab01b.cc
        > ./a.out

   Show same result with just g++ and then running a.out

        > g++ lab01b.cc
        > ./a.out

   Show that we can rename to lab01b.cpp and it doesn't matter.

         > mv lab01b.cc lab01b.cpp
         > g++ lab01b.cpp
         > ./a.out
 
   Show that we can name the executable something else with the -o switch:

   > g++ lab01b.cpp -o lab01b
   > ./lab01b

   You need the . if "." is not in your path
   > ./lab01b

   You don't need the . if "." is in your path
   > lab01b

   How do we know if . is in the path?

   > echo $PATH

   How do we change our path (under csh or tcsh) ?
   What is csh or tcsh?

      emacs ~/.cshrc
      emacs ~/.localenv

   Using the "which" command to know where the compiler is
   coming from.
