3. Example of STL containers

• Using prefabricated templates from the STL library is easy:

  
      #include <vector>
      #include <string>
  
      using namespace std;
  
      int main (int argc, char* argv[])
      {
          vector< double > vd; // vd elements are floating point numbers
          vector< int > vi;    // vi elements are integer numbers
          vector< string > vs; // vs elements are string objects
          return 0;
      }
  
  

• The typenames which appear inside angled brackets are template parameters.
