int main() {
    int reverse = 0, digit, num, mod;
    printf("Enter a positive Integer\n");
    scanf("%d", &num);
 
    /* reverse the input number */
    while (num > 0) {
        reverse = (reverse * 10) + num % 10;
        num /= 10;
    }
    num = reverse;
 
    while (num > 0) {
        digit = num % 10;
        printDigit(digit);
        num = num / 10;
    }
         
 getch();
    return 0;
}
 
void printDigit(int digit){
 switch (digit) {
        case 0:
