// L-1 MCS 360 Mon 23 Aug 2010 : hello_world.cpp

/* Our first C++ program writes "Hello World!" to screen.

We illustrate several aspects in this simple program:
(1) the include directive for the preprocessor
(2) using the standard (std) namespace of C++
(3) writing strings to standard output

To run the program, save the code in a file with name "hello_world.cpp" 
and type at the command prompt $ in a Terminal window:

$ g++ -o /tmp/hello_world hello_world.cpp

which invokes the C++ compiler in gcc, sending the output 
executable file into the /tmp folder with name "hello_world".
Typing /tmp/hello_world at the prompt will then run the program.  */
