using namespace std;
class time24
{
private:
int hours;
int minutes;
int seconds;
public:
time24() : hours(0),minutes(0),seconds(0)
{ }
time24(int h,int m,int s) :
hours(h),minutes(m),seconds(s)
{ }
void display(const)
{
if(hours<10) cout<<"0";
cout<<hours<<": ";
if(minutes<10) cout<<"0";
cout<<minutes<<":";
if(seconds<10) cout<<"0";
cout<<seconds<<":";
}
int gethrs() const {return hours;}
int getmins() const {return minutes;}
int getsecs() const {return seconds;}
};
class time12
{
private:
bool pm;
int hrs;
int mins;
public:
time12() :pm(true),hrs(0),mins(0)
{ }
time12(time24);
time12(bool ap, int h, int m) : pm(ap),hrs(h),mins(m)
{ }
void display() const
{
cout<<hrs<<":";

}
};
time12::time12(time24 t24)
{
int hrs=t24.gethrs();

mins=(t24.getsecs()<30)?
t24.getmins():t24.getmins()+1;
if(mins==60)
{
mins=0;
++hrs24;
if(hrs == 12||hrs == 24)

}

}
int main()

t24.display();
time12 t12=t24;
cout<<"\n12 hour time: ";
t12.display();
cout<<endl;
}
return 0;
}

Answer 3

here is the code...

Answer 4

wow thats a nice but no matter how i try to look at. but there are some errors....but check thoo. will advise to run in a true Compiler. will point out The errors..

class 12
{private..................
time12():pm(true),hrs(0),mins(0) {}
time12(time24);
time 12(bool ap);
int h, m;
pm(ap) //ap here wasn't Declared and also not a type

time12 does not have any field named *pm* or *hrs* or *mins* nd others
just run it in a compiler
