I have these code of lines from a program my teacher made :
TimeKeeper& operator++() {
d_seconds++;
return *this;
}
const TimeKeeper operator++(int) {
TimeKeeper tk(*this);
++(*this);
return tk;
}
And one of the questions my teacher asked us was "operator++() returns a reference and operator++ (int) returns a value, explain why?"
Can anyone explain this to me?? If you need the rest of the code i dont mind putting it on! Thanks!!
