resize() [1/3]

void resize

(

std::size_t

new_size

)

Changes the size of the vector default-constructing new elements, if necessary. .

Parameters

new_size

The desired size of the vector. If the value is less than the current size of the vector, the excessive elements are removed from the end of the vector. If the value is greater than the current vector size, new elements are default-constructed at the end of the vector. No copying takes place, thus the elements are not required to be copy-constructible nor copy-assignable.
