dateType class + increment day function

[xicestorm]

I am working with a dateType class and need to make a function to show next day and the previous day. I have my function set using const keyword so that it can't be changed by users, but now I can't increase my day. help???

int dateType::nextDay() const
{
getDay();
dDay++;
return dDay;
}
int dateType::previousDay() const
{
getDay();
dDay--;
return dDay;
}

Functions can't be edited by users anyway. When a function is const, it means that function can't change anything outside of it, which in your case is dDay. Get rid of the const and it'll work.
