Answer 1

#include <iostream>
using namespace std;
class time{
private:
int hours;
int minutes;
public:
time() {
hours=0;
minutes=0;
}
time(int h,int m){
hours=h;
minutes=m;
}
void displaytime(){
cout<<hours<<":"<<minutes<<endl;
}
time operator++ ()
{
++minutes; // increment this object
if(minutes >= 60)
{
++hours;
minutes -= 60;
}
return time(hours, minutes);
}
};

int main() {
time T1(11, 59);
++T1; // increment T1
T1.displaytime(); // display T1
++T1; // increment T1 again
T1.displaytime(); // display T1

return 0;
}

didn't get your question properly

but this is one of the examples for ++ operator overloading
copy paste on your compiler and compile you will understand
