Question

C and I’m working on a speaking clock. My problem is that I can save the time (hour and minute) in two NSIntegers but I can’t compare them.

The concrete problem is that I want to separate the time (for example the hour is stored in the NSInteger like this: 16. I want to get a 1 and a 6 separately). I want to separate one digit from the other digit to compare them.

Can anybody help me? A good compare syntax also will be a big help! Thanks.

Answer 1

If I understood your request, you want to separate the the whole number into digits from 0-9?

you could do it like this:

int hours = 16
int hour1 = hours / 10;
int hour2 = hours - hour1
hour2     = hours % 10;

int minutes = 47;
int minute1 = minutes / 10;
int minute2 = minutes - minute1;
minute2 = minutes % 10;
