I need to write a program with a class called CheapWatch

[Eddie Sardinha]

I have a C++ programming assignment due today and I am having trouble getting it to work correctly. Here is the assignment:

Write a program with a class called CheapWatch that provides the time of day in a program. Three unsigned integers should be used to represent time:

The first integer should represent the hour.
The second integer should represent the minutes.
The third integer should represent the seconds.


Include in the program a type conversion constructor that converts a long integer representing the number of seconds from midnight into your three-integer (hour, minute, second) representation. For example, if the long integer 18637 should convert to 5:10:37, you may use the following formula:

Elapsed seconds = (hours * 3600) + (minutes * 60) + seconds.


Use military time. For example, 3:40 PM is represented as 15:40:00.

#include <iostream>
#include <iomanip>

 using namespace std;
 
class cheap_watch
 {
 private :
 unsigned hr , minute , second;
 public:
 char ch;
 
cheap_watch(int a,int b,int c,char cha)
 {
 hr=a;
 minute=b;
 second=c;
 ch=cha;
 }
 
cheap_watch(unsigned num)
 {
 hr=static_cast<int>(num/3600);
 minute= static_cast<int>(((num/3600)-hr )* 60);
 second=static_cast<int>((((( (num/3600)-hr )*60)-minute))*60);
 };
 
void print_in_military_form()
 {
 if(ch == 'p' || ch =='P')
 hr=hr+12;
 if (hr<10)
 cout<<"0"<<hr<<":";
 else
 cout<<hr<<":";
 
if(minute<10)
 cout<<"0"<<minute<<":";
 else
 cout<<minute<<":";
 if(second<10)
 cout<<"0"<<second<<endl;
 else
 cout<<second<<endl;
 }
 };
 
void main()
 {
 
unsigned seconds;
 cout<<"please enter the number of seconds after midnight"<<endl;
 cin>>seconds;
 cheap_watch time(seconds);
 time.print_in_military_form();
 
}

This is what I have so far, when I run it I don't get the correct output.

add a prtottype of print_int_miltary_form() in the cheap_watch class declaration, and in the type casting ctor, add hr>12?ch='p':ch=a and it should work. I'm gonna try it out on my comp, and i'lll tell you the results.
EDIT: sorry, I just brealised that print_in_military_form() is already inside the class, sorry. And, you actualy don't need to add that ch assignment. But you do need to add some type-casting to double, or you'l get all zeros except for hours.

Thanks, but how do I do that?

[TightCoder]

Try this framework.

1: Why 'p' or 'P' your not asking for it anywhere
2: A calculation 71100 % 3600 = 19, so there is no need to convert as you did in 31 - 35

#include <iostream>
using namespace std;

class cheap_watch {
    int Hr, Min, Sec;
  public:
    void set_values ( int );
    void Show ( void );
};

void cheap_watch::set_values ( int ) {
	// Code that will convert seconds to Hr/Min/Sec
	}
	
void cheap_watch::Show ( void ) {
	// Output formatted military time
	}

int main () {
	int Seconds;
  	cheap_watch Clock;
  	
  	cout << "Enter seconds: " << endl;
  	cin >> Seconds;
  	Clock.set_values ( Seconds );
  	Clock.Show ();
  	return 0;
	}

[Eddie Sardinha]

Thanks, but this just displays the seconds I entered. How do I get it to print the hour, minutes and seconds in military time? How would I finish that?

[TightCoder]

You sort of worked it out in 23 - 25. I never checked to see if it worked but it could be done like this

void cheap_watch:: set_values ( int Secs ) {
    Hr = Secs / 3600;
    Min = (Secs % 3600) / 60;
    Sec = Secs % 60;
    }

Now all you have to do is designed the code in Show that will display HH:MM:SS and set_values has already determined 24 hr.

[Eddie Sardinha]

I'm confused about this part "Now all you have to do is designed the code in Show that will display HH:MM:SS and set_values has already determined 24 hr"

Do I add this in after the return 0; and what is "designed the code"?

Sorry this is really my first programming class

[TightCoder]

Your code to output formatted string goes in line 16. Please qualify what you mean by first programming class. Have you not learned anything about C++ before being given this assignment?

[Eddie Sardinha]

No, I mean this is the first C++ class I've taken and any help would be appreciated. I don't have help from anyone else.
