Explanation:
#include <iostream>
using namespace std;
class NumDays{
int hours;
float day;
public:

{

day=0.0;
};
NumDays(int h)
{

};
int getHour()
{
return hours;
}

{
return day;
}
NumDays operator +(NumDays obj)
{
int h=getHour()+obj.getHour();
NumDays temp(h);
return temp;
}
NumDays operator -(NumDays obj)
{
int h=getHour()-obj.getHour();
NumDays temp(h);
return temp;
}
const NumDays& operator++() //prefix
{

}

return temp;
}
};
int main()
{

cout<<"'obj3=obj2-obj'=> Day:"<<obj3.getDay()<<"##Hour:"<<obj3.getHour()<<"\n";
