Answer 1

The following program does what you want:

#include 

int main()
{

    int num =0;
    int power=1;

    printf("Enter any number:");
    scanf("%d",&num);

    while(num>power)
      power*=10;

    power/=10;

    while(num != 0)
    {
        int digit = num /power;
        printf("%d\n", digit);
        if(digit!=0)
          num=num-digit*power;
        if(power!=1)
          power/=10;
    }



    return 0;
}
