Create a vector of the specified `initialSize` whose every element is a default‐constructed object of the (template parameter) type `VALUE_TYPE`. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is not specified, a default‐constructed object of the (template parameter) type `ALLOCATOR` is used. If the type `ALLOCATOR` is `bsl::allocator` and `basicAllocator` is not supplied, the currently installed default allocator is used. Throw `std::length_error` if `initialSize > max_size()`. This method requires that the type `VALUE_TYPE` be `default‐insertable` into this vector (see {Requirements on `VALUE_TYPE`}). Note that a `bslma::Allocator *` can be supplied for `basicAllocator` if the type `ALLOCATOR` is `bsl::allocator` (the default).
