class TIME
{
int hour , min , sec ;
public :
TIME()
{
hour=min=sec=0;
}
TIME( int h , int m , int s )
{
hour = h;
min = m;
sec = s;
}
void change ( int Hour)
{
hour = Hour;
}
void stdtime()
{
if(hour>12)
cout<<"The Standard time is"<<(hour-12)<<":"<<min<<":"<<sec<<"P.M\n";
else
cout<<"The Standard time is"<<hour<<":"<<min<<":"<<sec<<"A.M\n";
}
void miltime()
{
cout<<"The Military time is"<<hour<<":"<<min<<":"<<sec<<" hours\n";
}
};
void main()
{
TIME A , B(13,25,30);
A .stdtime();
A.change(23);
A.miltime();
B.stdtime();
B.change(9);
B.miltime();
}

class elevator
{
int CurrentFloor;
int GoingUp;
int GoingDown;
public:
elevator()
{
CurrentFloor=0;
GoingUp=1;
GoingDown=-1;
}
elevator(int floor)
{
CurrentFloor=floor;
GoingUp=1;
GoingDown=-1;
}
void goUp(int y)
{
if( CurrentFloor>3)
cout<<"\nNO MORE FLOORS\n";
else
CurrentFloor=CurrentFloor+y*GoingUp;
}
void goDown(int x)
{
if(CurrentFloor<0)
cout<<"\nNO MORE FLOORS";
else
CurrentFloor=CurrentFloor+x*GoingDown;
}
};
void main()
{
elevator A(1);
A.goUp(1);
A.goUp(1);
A.goUp(1);
A.goDown(1);
A.goDown(1);
}
I believe that answer A is true
