#include<conio.h>
class Time
{
int minutes,hours,a;
static int i;
public:

{
this->a=hours=a;
this->a+=5;

cout<<"\nObj address : "<<this;
cout<<"\nAddress of i : "<<&i;
cout<<"\na= "<<this->a<<"\t\t"<<a;
getch();
}
~Time()
{
cout<<endl<<"\t\t"<<hours<<" : "<<minutes;
getch();
}
};
int Time ::i;
void main()
{
clrscr();
Time t3(10),t2(1);
}
