when a vector in c++ is resized what happens to the elements of the vector
The C++ function std::vector::resize() changes the size of vector. If n is smaller than current size then extra elements are destroyed.
If n is greater than current container size then new elements are inserted at the end of vector.
If val is specified then new elements are initialed with val.
