Returns the number of elements in the vector. This is the number of actual objects held in the vector, which is not necessarily equal to its storage capacity. |
unsigned int size() const
. It will return the number of elements the vector contains (literally; 0 = no elements, (so your_vector.size() - 1)
would be the very last element).
