    problem: cant acess class methods using vectors

    now i have a class Schedule.
    Code:
    class Schedule
    {
    public:
    	Schedule(int &dailyCounter)
    {	cout<<"In Daily ctor"<<endl;
    	dailyCounter++;
    };
    	~Schedule(){cout<<"in daily dtor"<<endl;};
    	void printSchedule()
                     {cout<<"PrintSchedule"<<endl;};
    private:
    	int dailyCounter;
    
    };
    in main i do...
    Code:
      int i=0;
      static std::vector <Schedule> newdaily;
    for(i=0;i<10;i++)
    {  Schedule tempDaily = Schedule::Schedule(i);
      newdaily.push_back(tempDaily);
      newdaily[i].printSchedule();
    }
    it gives me error at this line in main
    it gives that object couldnt get created
    newdaily[dailyCounter].printSchedule;
    why i cant acess a method of Schedule using vector indexing...

    ignore this line at the end
    newdaily[dailyCounter].printSchedule;

    and cosider this correct
    newdaily[i].printSchedule();

    This line is rather suspect:
    Code:
    Schedule tempDaily = Schedule::Schedule(i);
    The constructor isn't static, so call it like this:
    Code:
    Schedule tempDaily(i);
    The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.

    ok i tried this and thsi isnt working too
    neither in VC++ nor on Solaris GNU compiler
    Code:
    class Schedule
    {
    public:
    	Schedule()
                       {cout<<"In Daily ctor"<<endl;};
    	~Schedule(){cout<<"in daily dtor"<<endl;};
    	void printSchedule()
                     {cout<<"PrintSchedule"<<endl;};
    private:
    
    };
    --------------------------------------------------------------------------------

    in main i do...

    Code:
      int i=0;
      static std::vector <Schedule> newdaily;
    for(i=0;i<10;i++)
    {  Schedule tempDaily();
      newdaily.push_back(tempDaily);
      newdaily[i].printSchedule();
    }
    but still the same error

    well here is an exact code extract from what i did, it works fine, can't understand why you are having that problem.

    Code:
    #include <iostream>
    #include <vector>
    
    using namespace std;
    
    class Schedule
    {
      public:
    	Schedule(int &dailyCounter)
            {
              cout<<"In Daily ctor"<<endl;
    	  dailyCounter++;
            };
    	~Schedule(){cout<<"in daily dtor"<<endl;};
    	void printSchedule(){cout<<"PrintSchedule"<<endl;};
    private:
    	int dailyCounter;
    };
    
    
    int main(void)
    {
      int i=0;
      static std::vector <Schedule> newdaily;
      for(i=0;i<10;i++)
      {
        Schedule tempDaily(i);
        newdaily.push_back(tempDaily);
        newdaily[i].printSchedule();
      }
      return 0;
    }

    Code:
    Schedule tempDaily( );
    Give it the parameter:
    Code:
    Schedule tempDaily(i);

    Once you get it to compile, you should notice that the rest of your original code doesn't do what you want it to do. You can try to figure out what I'm talking about on your own, but a hint is to look at your constructor incrementing dailyCounter. Which dailyCounter variable is it incrementing? If that is what you meant to do, then what are the effects when the incremented variable is used later?
