Templates let us write a single class or function definition that can be used on a variety of types. • To declare objects from a class template, we must supply additional information. In the case of vector, we must say what type of objects the vector will contain: vector<int> intVector (MAX_ELE_NUM); vector<LineT> lineVector (100);
