With the whole CLI, CTS, CLS, etc., not only did they release a powerful platform/infrastructure, but they released all the specs that describe it etc. It supports potentially infinite myriad languages, platforms, etc. This seems like an insane amount of work, even for a behemoth like Microsoft - especially since it tu... |
For every programming project, managers with past programming experience try to shine when they recommend some design patterns for your project. I like design patterns when they make sense or if you need a scalable solution. I've used Proxies, Observers and Command patterns in a positive way for example, and do so ever... |
That's just an example case. What I'm trying to point out is, how can you claim something (software/website/or any 'ontouch-able' products) as yours while at the same time you are using some existing technologies behind it? (such as database engine, programming languages, compilers, or even the computer it self!).
If y... |

I've seen that there are several different paradigms in C++ concerning what goes into the header file and what to the cpp file. AFAIK, most people, especially those from a C background, do:

public:

I'm largely a self-taught programmer.

C::C(int foo) {
