Hello, smeeld, you wrote: S> Here asked questions about the spherical commercial code, type that this such and as it looks. Further two links implementing different principles of creation of parcers what of them, according to local audience, is more to be accepted to the concept standard of "the commercial code". Yes any, for a question - silly! There is no such "commercial" code. There are tasks and the whole heap of the parameters influencing the future code. Same "sorting" can be made by 10 different methods (not algorithm!) Depending on requirements. For example: the program is necessary "still yesterday", therefore QUICKLY do any prototype if only the output was correct. Criterion - speed of development, templates and space architecture go wood. The program will be supported by the school teacher, therefore the code should be idle time and even without classes. The program is necessary for embedded, therefore you have two variables and 1 storages - both want, and write. The program is necessary for on RSDN, therefore stuff there more templates - people love it. Well and what sense at absolutely unknown criteria to compare two the code?? You, a companion smeeld, how many months in programming?
