The program demonstrates several modern C++ features by enhancing the counter class from the previous project, these features are:
- Reference member variables
- Member function ref-qualifications
- Value category based function overloading
- Move semantics (in the rvalue version)
This design allows for:
- Direct manipulation of the counter's value through either value or ref_value
- Different behavior based on whether operations are performed on temporary or named objects
- Type-safe operations that prevent misuse of temporary objects
- Clear distinction between operations on persistent objects vs temporary ones
The combination of reference members and ref-qualified functions makes this a good example of how C++ can enforce proper object lifetime and value category semantics while maintaining efficiency and safety.
- ref_counter.h (Header file with class declaration)
- ref_counter.cpp (Implementation file with method definitions)
- counter_test.cpp (Test file with assertions)
- Makefile (Build automation)
- The Makefile uses g++ compiler with warnings (-Wall) and debug info (-g)
- Compiles source files into object files (.o)
- Links object files into final executable
- Automatically handles dependencies (recompiles only when needed)
make
# or
make all # This compiles all source files and creates the executable counter_test.exe
make run # This builds (if needed) and executes the program
make test.log # This runs the program and saves output to counter_test.log
make clean # Removes all generated files (executable, object files, logs)- Headers are properly guarded against multiple inclusion
- Test file includes assertions to verify class functionality
- Build process follows standard C++ compilation model
