Convert integer to array

Question

I would like to convert an integer into an array, so that it looks like the following:

int number = 123456 ;
int array[7] ;

with the result:

array[0] = 1 
array[1] = 2
...
array[6] = 6

Answer 1

Perhaps a better solution is to work backwards:

123456 % 10 = 6

123456 / 10 = 12345

12345 % 10 = 5

12345 / 10 = 1234

Answer 2

just use modular arithmetic:

int array[6];
int number = 123456;
for (int i = 5; i >= 0; i--) {
    array[i] = number % 10;
    number /= 10;
}
