You can do it with this function:

void printDigits(int number) {
    if (number < 0) { // Handling negative number
        printf('-');
        number *= -1;
    }
    if (number == 0) { // Handling zero
        printf('0');
    }
    while (number > 0) { // Printing the number
        printf("%d-", number % 10);
        number /= 10;
    }
}
