Structure of a C++ program using classes

Source files

• Header file for a class definition, JarType.h in the Cookie Jar example.
• Implementation file for a class definition, JarType.cpp in the Cookie Jar example.
• Test driver for testing a new class definition, testJarType.cpp in the Cookie Jar example.

Compiling

• Prepare a Makefile with all the dependencies between files, and specifying how to produce the executable file from source files.
• The Makefile has to be in the same directory as the souce files.
• To compile, type
  
  make
  
  at the Unix prompt, in the directory where you want to do the compilation.

Files produced by the compilation and how to execute

• Object files. For example, JarType.o contains the object file for the class JarType.
• The executable file, testJarType.
• To execute, type the name of the executable file,
  
  testJarType
  
  at the Unix prompt.
• Make sure the executable file has execute permissions. They should be automatically set by the compiler, but if for whatever reason they are not, change them using:
  
  chmod +x testJarType
