Code Reuse

By now you may have gotten the impression that object-orientated programming (OOP) often involves a lot of typing. But this is because OOP is not just about writing the current program, but the next version, and any similar programs. Only the smallest programs have no future development path, so it pays to take a little more trouble. OOP aims to provide a good foundation for further development.

Making code more reuseable is a practical way of improving programming productivity. Classes are often easier to reuse than libraries of plain functions (although they still have their place.) For example, it is easier to use string than to use the C-style string manipulation functions like strcpy(), and so forth.

Class frameworks are effectively ...
