Even this is difficult unless there is a good organizational structure. The organizational structure advocated by the preceding chapters results in good class implementation and Class Wizard is very helpful in maintaining that structure. This is particularly true when the class definition evolves. With Class Wizard evolution is a simple matter of adding elements to the definition and rebuilding the files. Files managed by the tool are overwritten with the new definition while handcrafted files are untouched. The best balance is always maintained between standard idioms and a developer s creativity. INDEPENDENT INVESTIGATIONS 1. Repeat the test-drive commands using cDiamond objects instead of cShape objects. 2. Modify the class interfaces to allow shapes to be rotated by an arbitrary angle. Use Class Wizard to generate the initial versions of helper functions and .
