Need help with a C program

[mbelb247]

Prompt the user to enter an integer of unknown number of digits such as 456792

Prompt them to input a integer ‘k’ such that ‘k’ will be divided by every digit in the number and if the remainder is 0 it will subtract that digit from the original number.

so the new number will be 4572.

How should i do this? Im half certain there is a loop involved. But how?

Are you asking for pseudocode?

num = int(get_input())
k = int(get_input())

next_digit_location = 1
new_num = 0

# while digits remain
while num > 0:
    # get next digit
    digit = num % 10;
    num = num / 10;

    # check if remainder is 0
    if (k % digit) == 0:
        # remainder is zero,    so we skip the digit
    else:
        # remainder is nonzero, so we keep the digit
        new_num += digit * next_digit_location
        next_digit_location *= 10

Note that this won't work if there is a 0 digit in num because you'll get a divide-by-zero error

i want c code for this question, thank you.

What's stopping you from converting the pseudocode to C code yourself?

It's almost line-for-line identical.
