Storing an int as individual digits in an array

I have an int i, say 6473, and I want to store each digit separately in an array, like so:

array[0] = 6;
array[1] = 4;
array[2] = 7;
araay[3] = 3;

How can I do this?

thx

What have you tried?

What is the problem, I would ask? You specifically mention an array - is the problem that you do not know how to create or declare an array?

I know how to declare an array, I just don't know how to split an int into an array.

Ah, now I understand. So basically, each digit into its own array. For that I would ask if you actually answer laserlight's question.
I could also provide some insight - how would you do it mathematically in the real world?

No that's not what I meant.

Think of it this way, ignore the whole array part, the question really is:

How would I access each individual digit of the number: 45656

i.e. what would I have to do to access the 4?

Suppose you divide the number by 10. What is the remainder?

Ah k, in the end I've just decided to convert to a string

Admittedly, it's possible without a string, but a bit tricky. Here's an example!

Code:

---

        const int mynum = 12345;
        int num1 = ( mynum - (mynum / 10 * 10) ) / 1;
        int num2 = ( mynum - (mynum / 100 * 100) ) / 10;
        int num3 = ( mynum - (mynum / 1000 * 1000) ) / 100;
        int num4 = ( mynum - (mynum / 10000 * 10000) ) / 1000;
        int num5 = ( mynum - (mynum / 100000 * 100000) ) / 10000;

---

num1 = 5, num2 = 4, num3 = 3, num4 = 2, num5 = 1

Might I suggest sprintf()...

Code:

---

char str[12];
int num = 12345;
sprintf( str, "%d", num );

---

Actually, it's not very difficult to do your own as long as you store the string from the back. But obviously much less code to use sprintf() [at least of code "that you write yourself"].

Arguably, the easiest way is to convert to string first, then take each element and covert back to integer again. Although the OP did specify that it was converted to a string in the end.
