About LinkBacksHi, i've tried look about for this but cant find it.
Basically all i want to do its break a number up into single ints.
I.E
id have
int a
int b
int c
and a number, say 189. I want break 189 into 1,8 and 9. So a=1 b=8 and c=9.
thanks for any help.

Use math, specifically division and modulus. What's (189 / 100) % 10 in integer math? It's 1. What's (189 / 10) % 10? It's 8. What's (189 / 1) % 10? It's 9.

Amen brother!
oh, so i cant just break it up you can in java?
If "189" is a string, then yes you can parse it out. You implied 189 was an integer by calling it a number, (and because you didn't put double quotes around it), thus you got a math solution.

Of course you can, and Daved explained how.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.

yeah it is an int i will be reading in.
so there is no classes to do this sort of thing? sorry im a noob at c++
in java i would just use the scanner and nextInt()
thanks for the replys.
No, you wouldn't do that in Java, as nextInt() only works with strings (you said it's an int) and would grab the entire number.
All the buzzt!

Or the std::stringstream class would work.
>> yeah it is an int i will be reading in
Or you might be able to read it in as a string and get each digit that way. To convert a single character to an int just subtract the zero character:Code:string num("189"); int second_digit = num[1] - '0'; // second_digit is 8.
