c++ function help

OK - please look at the following:

1. Please try to compile and run it.

Please cut/paste any compile/runtime errors you might encounter.

2. What's different between this code and your code?

Why?

3. What would you have done differently?

Code:

#include <iostream.h>

class  Time
{
  private:
    int hours;
    int minutes;
    int seconds;
    void setHour(int h);
    void setMinute(int min);
    void setSecond(int sec);
    void setTime(int hour, int minute, int second);

  public:
    Time();
    Time (int hh, int mm, int ss);
    void printStandard();
    void printMilitary();
};


// "Default" (no-argument) constructor
Time::Time ()
{
  setTime(0,0,0); 
}

// Overloaded constructor
Time (int hh, int mm, int ss)
{
  setTime(hh, mm, ss); 
}

void 
Time::setHour(int h)
{
  hours = (h >= 0 && h < 24) ? h : 0;
}

void 
Time::setMinute(int min)
{
  minutes = (min >= 0 && min < 60) ? min : 0;
}

void 
Time::setSecond(int sec)
{
  seconds = (sec >= 0 && sec < 60) ? sec : 0;
}

void 
Time::setTime(int hour, int minute, int second)
{
  setHour(hour);
  setMinute(minute);
  setSecond(second);
}

void 
Time::printStandard()
{
  //print leading zeroes; for example 03, not just 3
  cout << "The Time is " 
    << ( hours > 12 ? hours-12 : hours) << ":"
    << ( minutes < 10 ? "0" : "") << minutes << ":" 
    << ( seconds < 10 ? "0" : "") << seconds 
    << ( hours < 12 ? " am" : " pm") << endl;

}

void Time::printMilitary()
{

  //print leading zeroes; for example 03, not just 3
  cout << "The Time is "
    << ( hours < 10 ? "0" : "") << hours << ":"
    << ( minutes < 10 ? "0" : "") << minutes << ":" 
    << ( seconds < 10 ? "0" : "") << seconds << endl;
}

int
main(int argc, char *argv[])
{
  Time myTime(4, 21, 4);
  myTime.printStandard();
  myTime.printMilitary();

  Time yourTime(3,2,24);
  yourTime.printStandard();
  yourTime.printMilitary();

  return 0;
}

}

That is what i have now andit still does not work.

Errors:
line 14 could not find a match for 'Time::Time(int,int,int)' in Function Time::Time()
line 14 could not find a match for 'Time::Time(int,int,int)' in Function Time::Time()
line 65 Undefined symbol 'myTime' in function main()
line 65 Undefined symbol 'yourTime' in function main()

What am i todo i am getting lost from all this help and explaining and showing of bits of code and not others. Can someone show what needs to be done to get this to work.

Thanks
Tim

This code is working . I compiled with UNIX
#include <iostream.h>

class Time
{
private:
int hours;
int minutes;
int seconds;
void setHour(int h);
void setMinute(int min);
void setSecond(int sec);
void setTime(int hour, int minute, int second);
public:
Time(int x=0,int y=0,int z=0) {setTime(x,y,z);

}
void printStandard();
void printMilitary();

};

void Time::setHour(int h)
{
hours = (h >= 0 && h < 24) ? h : 0;
}

void Time::setMinute(int min)
{
minutes = (min >= 0 && min < 60) ? min : 0;
}

void Time::setSecond(int sec)
{
seconds = (sec >= 0 && sec < 60) ? sec : 0;
}

void Time::setTime(int hour, int minute, int second)
{
setHour(hour);
setMinute(minute);
setSecond(second);
}

void Time:

rintStandard()
{

//print leading zeroes; for example 03, not just 3

cout << "The Time is " << ( hours > 12 ? hours-12 : hours) << ":"
<< ( minutes < 10 ? "0" : "") << minutes << ":" << (
seconds < 10 ? "0" : "") << seconds << ( hours < 12
? " am" : " pm") <<endl;

}
void Time:

rintMilitary()
{

//print leading zeroes; for example 03, not just 3

cout << "The Time is " << ( hours < 10 ? "0" : "") << hours << ":"
<< ( minutes < 10 ? "0" : "") << minutes << ":" << (
seconds < 10 ? "0" : "") << seconds << endl;

}

void main()
{
Time myTime(4, 21, 4);
Time yourTime(3,2,24);
myTime.printStandard();
yourTime.printMilitary();
}

It's because you had ":p". If you want to show things like that, then select the "Disable smileys in text" option below. Edit: also, please use code tags as it helps make your code more readable.

timay9162: are you squared away with what you were trying to get your C++ "Time" class to do?

Did this thread help:
http://www.linuxquestions.org/questi...7#post2157077?

Do you understand what your instructor was trying to get you to work out for this assignment?

Please do post back and let us know.

Thanx in advance ..

Code:

#include <iostream.h>

class  Time
  {
	 private:
		int hours;
		int minutes;
		int seconds;
		void setHour(int h);
		void setMinute(int min);
		void setSecond(int sec);
		void setTime(int hour, int minute, int second);
	 public:
		Time(int h = 0, int min = 0, int sec = 0) {setTime(h, min, sec);}
		void printStandard();
		void printMilitary();

  };

void Time::setHour(int h)
  {
	 hours = (h >= 0 && h < 24) ? h : 0;
  }

void Time::setMinute(int min)
  {
	 minutes = (min >= 0 && min < 60) ? min : 0;
  }

void Time::setSecond(int sec)
  {
	 seconds = (sec >= 0 && sec < 60) ? sec : 0;
  }

void Time::setTime(int hour, int minute, int second)
  {
	 setHour(hour);
	 setMinute(minute);
	 setSecond(second);
  }


void Time::printStandard()
  {
	 cout << "The Time is " << ( hours > 12 ? hours-12 : hours) << ":"
	 << ( minutes < 10 ? "0" : "") << minutes << ":" << ( seconds < 10 ? "0" : "") << seconds << ( hours < 12 ? " am" : " pm") <<endl;
  }

  void Time::printMilitary()
  {
	 cout << "The Time is " << ( hours < 10 ? "0" : "") << hours << ":"
	 << ( minutes < 10 ? "0" : "") << minutes << ":" << ( seconds < 10 ? "0" : "") << seconds << endl;
  }

void main()
  {
	 Time myTime(4, 21, 4), yourTime(3,0,0);
	 myTime.printStandard();
	 yourTime.printMilitary();
  }

there it is figured it out with help from everyone here i am positive this is the way my teacher wants the program to be. Itis a little different from what everyone on here has suggested but all your help got me to this point.

Thanks
Tim
