std::vector continuity

[Lynn]

Are std::vector items guaranteed to be continuous ?

For instance, if I have a "std::vector <char> text".
If I get a pointer "char *p = & text [0];", can use the
pointer to work thru the limits of the vector ?

Thanks,
Lynn McGuire

Yes, until you cause the capacity of the vector to change.

Yes. Well, they officially weren't before the 2003 version of the C++
standard, but there seems to be no known implementation that didn't store
the data continuously.

If I get a pointer "char *p = & text [0];", can use the
pointer to work thru the limits of the vector ?

Yes.
