operator==

template<class T, class A>
    bool operator==(
        const vector <T, A>& lhs,
        const vector <T, A>& rhs);

The template function overloads operator== to compare two objects of template class vector. The function returns lhs.size() == rhs.size() && equal(lhs. begin(), lhs. end(), rhs.begin()).
