经典书籍源代码啊。。。第三版。。。数据结构与算法分析——C++描述(第3版).

class Employee
{
  public:
    void setValue( const string & n, double s )
      { name = n; salary = s; }

    const string & getName( ) const
      { return name; }
    void print( ostream & out ) const
      { out << name << " (" << salary << ")"; }
    bool operator< ( const Employee & rhs ) const
      { return salary < rhs.salary; }

    // Other general accessors and mutators, not shown
  private:
    string name;
    double salary;
};

  // Define an output operator for Employee
ostream & operator<< ( ostream & out, const Employee & rhs )
{
    rhs.print( out );
    return out;
}

int main( )
{
    vector<Employee> v( 3 );

    v[0].setValue( "George Bush", 400000.00 );
    v[1].setValue( "Bill Gates", 2000000000.00 );
    v[2].setValue( "Dr. Phil", 13000000.00 );
    cout << findMax( v ) << endl;

    return 0;
}
