    Problems with skipws

    The program :
    ================
    Code:
    #include <iostream>
    using namespace std;
    
    int main () {
      int n;
      cin >> skipws >> n;
      cout << n << endl;
      return 0;
    }
    ================

    upon compilation throws up the following errors:

    ====================================
    # g++ skipws.cpp
    skipws.cpp: In function `int main()':
    skipws.cpp:6: `skipws' undeclared (first use this function)
    skipws.cpp:6: (Each undeclared identifier is reported only once
    skipws.cpp:6: for each function it appears in.)

    ====================================

    upon modification to:
    =========================
    Code:
    #include <iostream>
    using namespace std;
    
    int main () {
      int n;
      cin >> ios::skipws >> n;
      cout << n << endl;
      return 0;
    }
    =========================

    It now throws up the error:
    ====================================
    # g++ skipws.cpp
    skipws.cpp: In function `int main()':
    skipws.cpp:6: initializing non-const `int &' with `ios::{anonymous enum}' will use a temporary
    //usr/lib/gcc-lib/ntox86/2.95.3/../../../../include/g++-3/iostream.h:206: in passing argument 1 of `istream:perator >>(int &)'

    ====================================

    How do I solve this? Any thoughts?

    Code:
    #include <iostream>
    #include <iomanip>
    using namespace std;
    
    int main ()
    {
        int n;
        cin >> setiosflags(ios::skipws) >> n;
        cout << n << endl;
        return 0;
    }
