When would you use an array rather than a vector/string?

Question

I\'m a beginner C++ programmer and so I\'ve learnt using arrays rather than vectors (this seems to be the general way to do things, then move on to vectors later on).

Answer 1

When writing code that should used in other projects, in particular if you target special platforms (embedded, game consoles, etc.) where STL might not be present.

Old projects or projects with special requirements might not want to introduce dependencies on STL libraries. An interface depending on arrays, char* or whatever will be compatible with anything since it's part of the language. STL however is not guaranteed to be present in all build environments.
