Hi,

Does anyone know whether there is function in c++ as the
function realloc in c? How can I re-allocate memory when I
find the memory allocated by new is not enough?

Thanks in advance,
Andy

You can't.

In many cases though, this means that you should probably be using
std::vector instead of allocating an array yourself.  std::vector takes care
of reallocating memory when necessary so you don't have to worry about it.

You can't.  You have to allocate and copy.

It's been suggested that some kind of realloc should be added to
allocators in the next round of the standard so that the standard
containers can extend their current allocation on expansion (if
possible) instead of doing an allocate and copy.
