    Question Problem with class/derived class

    Ok...i dont know how this is giving me an error- i have checked with so many sources including my notes from class and it matches with what I have but the compiler is giving me this error:
    Code:
    135: error: expected unqualified-id before { token
    135: error: expected `)' before { token
    here is my WHOLE program....the teacher gave us the whole base class- and we had to do the derived class from it. I have not put the print function in yet but i will after i can get this to work!!! Please someone help!!!!!!

    Code:
    #include <iostream>
    #include <string>
    using namespace std;
    
    class clockType
    {
    public:
      void setTime(int hours, int minutes, int seconds);
      void getTime(int& hours, int& minutes, int& seconds) const;
      void printTime() const;
      void incrementSeconds();
      void incrementMinutes();
      void incrementHours();
      bool equalTime(const clockType& otherClock) const;
      clockType(int hours, int minutes, int seconds);
      clockType();
    
    private:
      int hr, min, sec;
    };
    
    void clockType::setTime(int hours, int minutes, int seconds)
    {
      if (0 <= hours && hours < 24)
        hr = hours;
      else
        hr = 0;
      if (0 <= minutes && minutes < 60)
        min = minutes;
      else
        min = 0;
      if (0 <= seconds && seconds < 60)
        sec = seconds;
      else
        sec = 0;
    }
    
    void clockType::getTime(int& hours, int& minutes, int& seconds) const
    {
      hours = hr;
      minutes = min;
      seconds = sec;
    }
    
    void clockType::incrementHours()
    {
      hr++;
      if (hr > 23)
        hr = 0;
    }
    
    void clockType::incrementMinutes()
    {
      min++;
      if (min > 59)
       {
         min = 0;
         incrementHours();
       }
    }
    
    void clockType::incrementSeconds()
    {
     sec++;
     if (sec > 59)
      {
       sec = 0;
       incrementMinutes();
      }
    }
    
    void clockType::printTime() const
    {
     if (hr < 10)
       cout << "0" << hr << ":";
     if (min < 10)
       cout << "0" << min << ":";
     if (sec < 10)
       cout << "0" << sec;
    }
    
    bool clockType::equalTime(const clockType& otherClock) const
    {
      return (hr == otherClock.hr && min == otherClock.min && sec == otherClock.sec);
    }
    
    clockType::clockType(int hours, int minutes, int seconds)
    {
      if (0 <= hours && hours < 24)

    You forgot the class scope identifier on your second constructor.

    thanks so much- must have overlooked it (a thousand times). Thanks again!
