Effects: If sz < size(), erases the last size() - sz elements from the sequence. Otherwise, appends sz - size() default-inserted elements to the sequence.
Requires: T shall be MoveInsertable and DefaultInsertable into *this.
void resize(size_type sz, const T& c);
Effects: If sz < size(), erases the last size() - sz elements from the sequence. Otherwise, appends sz - size() copies of c to the sequence.
Requires: T shall be CopyInsertable into *this.
Requires: T shall be MoveInsertable into *this.
Effects: shrink_to_fit is a non-binding request to reduce memory use but does not change the size of the sequence. [ Note: The request is non-binding to allow latitude for implementation-specific optimizations. — end note ] If an exception is thrown other than by the move constructor of a non-CopyInsertable T there are no effects.
Complexity: Linear in the size of the sequence.
Remarks: shrink_to_fit invalidates all the references, pointers, and iterators referring to the elements in the sequence.
