Prototype (C++ tutorial) - Design Patterns

Creating a lot of marginally different objects can be costly, both in terms of runtime performance and productivity. Let me show you a pattern which solves that problem.

This is the first time ever I saw you using the "class" keyword. :)

hi and thanks for the share. One thing I don't understand : what's the point of this pattern in C++ over copy constructor ? in reference based languages that don't have copy constructor like java or c#, among others, ok I understand, but for C++, I don't really get it.
coz in the end, we have to implement the clone method in that pattern just as we would have to reimplement the copy constructor.

But here your using Shallow Copy .

Changing the color in any car changes the color of all other clones including the prototype.

One of the patterns I do not like... Thank you for the video and for mentioning expensive c-tor.

useful but why don't you use "using namespace std;" ?

EXC_BAD_INSTRUCTION after doing this code :/
