multiset cbegin() and cend() function in C++ STL

  1. The multiset::cbegin() is a built-in function in C++ STL which returns a constant iterator pointing to the first element in the container. The iterator cannot be used to modify the elements in the set container. The iterators can be increased or decreased to traverse the set accordingly.

    Syntax:

    constant_iterator multiset_name.cegin()
    

    Parameters: The function does not accept any parameters.

    Return value: The function returns a constant iterator pointing to the first element in the container.



    Below programs illustrate the multiset::cbegin() method.

        int arr[] = { 14, 10, 15, 11, 10 };
      
        // initializes the set from an array
        multiset<int> s(arr, arr + 5);
      
        // Prints the first element
        cout << "The first elements is: " << *(s.cbegin()) << endl;
      
        // prints all elements in set
        for (auto it = s.cbegin(); it != s.cend(); it++)
            cout << *it << " ";
      
        return 0;
    }

    Output:

    The first elements is: 10
    10 10 11 14 15
    
  2. The multiset::cend() is a built-in function in C++ STL which returns a constant iterator pointing to the position past the last element in the container. The iterator cannot be used to modify the elements in the set container. The iterators can be increased or decreased to traverse in the set accordingly.

    Syntax:

    constant_iterator multiset_name.cend()
    

    Parameters: The function does not accept any parameters.

    Return value: The function returns a constant iterator pointing to the position past the last element in the container in the container.

        multiset<int> s(arr, arr + 8);
      
        // prints all elements in set
        for (auto it = s.cbegin(); it != s.cend(); it++)
            cout << *it << " ";
      
        return 0;
    }

    Output:

    10 10 11 14 15 15 17 17
