Convert C-Style String to an Integer Array

I have 2 functions, they are called SplitInt(unsigned int x) and SplitChar(char x[])

SplitInt takes in any positive integer, such as 12345, and puts each digit into an integer array, but backwards. So for SplitInt(12345) the array would look like this:

array[0] = 5
array[1] = 4
array[2] = 3
array[3] = 2
array[4] = 1

SplitChar() is supposed to do the same thing but take in a C-Style string, such as "12345".

How would I separate the individual digits and send them into an integer array? I am not allowed to use string class.

Thanks!

#define MAX_STR_LENGTH 100

int array[MAX_STR_LENGTH];

int SplitChar(char x[])
{
    int len = strlen( x );

    if ( len > MAX_STR_LENGTH )
        return -1;

    int i = 0;

    while ( i < len )
    {
        array[len-i-1] = x[i] - '0';
        i++;
    }

    return len;
}

Returns the length of the string or -1 if too long.
