Clean destruction of a vector of dynamically alocated objects

Is there another way of freeing the memory of the alocated objects, rather than iterating through the vector/list? 

int main()
        {
            vector<Class*> v;
            v.push_back(new Class(2,2));
            v.push_back(new Class(65,65));
            v.push_back(new Class(45,23));
            for(Class* &it : v)
               delete it;
            return 0;
        }

yes there is. it is called smart pointers:

std::vector<std::unique_ptr<Class>> v;
v.push_back(std::make_unique<Class>(Class(2,5)));

However if you don't have a reason to use dynamically allocated objects, prefer std::vector<Class>.
