CS222 Lab 6
Lab 6 - Seperate Compilation and Namespaces
The purpose of this lab is to learn how to create multiple files for seperate
compilation and how to use programmer-defined namespaces.
Part 1 - Seperate Compilation
Take the code from Display 12.5 in the book and
convert it to use seperate compilation. Put the function prototypes for each
namespace into a file called "greeting.h". Put the function bodies for each
namespace into a file called "greeting.cpp". Finally, put the main function
into a file called "lab6.cpp". In the greeting.h file, make sure to include
the #ifndef directive to make sure multiple copies of the file are not
included.
Compile greeting.cpp and lab6.cpp using
g++ -c <filename>
Link the files together to make the executable using
g++ -o lab6 greeting.o lab6.o
Part 2 - Namespaces
Extend the namespaces in greeting.h and greeting.cpp to include the function
void farewell();. The bodies for each farewell function should
be different. Modify main.cpp to call farewell(); in each
namespace.
What to turn in
Email the files greeting.h, greeting.cpp and lab6.cpp that have the changes
you made in Part 2. In the body of the email, cut and paste a log of you
using g++ -c <filename> to compile greeting.cpp and lab6.cpp
and of you using g++ -o lab6 greeting.o lab6.o to create the
executable.
