Some variations have been omitted from the diagram for the sake of clarity: type qualifiers such as const and storage class specifiers such as static can appear in any order within the declaration, as long as neither immediately follows the keyword vector (or __vector). Vector declaration ...
This method returns the number of elements that can be inserted in the vector based on the memory allocated to the vector. atfunction This method works same in case of vector as it works for array.vector_name.at(i)returns the element atithindex in the vectorvector_name. ...
