void deallocate(pointer p, size_type n);
pへの以前の呼び出しによって得られたポインタでなければならないポインタallocate()によって参照されるストレージは、割り当てを解除します。引数nはもともとallocate()を生産pへの呼び出しの2番目の引数に等しくなければなりません.
Original:
Deallocates the storage referenced by the pointer p, which must be a pointer obtained by an earlier call to allocate(). The argument n must be equal to the second argument of the call to allocate() that originally produced p.
