Are std::vector elements guaranteed to be contiguous?

Question

My question is simple: are std::vector elements guaranteed to be contiguous? In order word, can I use the pointer to the first element of a std::vector as a C-array?

Answer 1

As other answers have pointed out, the contents of a vector is guaranteed to be continuous (excepting bool's weirdness).

The comment that I wanted to add, is that if you do an insertion or a deletion on the vector, which could cause the vector to reallocate it's memory, then you will cause all of your saved pointers and iterators to be invalidated.
