How do I split an int into its digits?

Question

How can I split an int in c++ to its single numbers? For example, I\'d like to split 23 to 2 and 3.

Answer 1

    int power(int n, int b) {
    int number;
    number = pow(n, b);
    return number;
}


void NumberOfDigits() {
    int n, a;
    printf("Eneter number \n");
    scanf_s("%d", &n);
    int i = 0;
    do{
        i++;
    } while (n / pow(10, i) > 1);
    printf("Number of digits is: \t %d \n", i);

    for (int j = i-1; j >= 0; j--) {
        a = n / power(10, j) % 10;
        printf("%d \n", a);
    }
}

int main(void) {
    NumberOfDigits();
}
