What is the following code doing? while ((1 scanf("%d", &k)) && (k % n- 0)) { - Number k is read repeatedly from the terminal until k is 1 and the loop repeats if k is divisible to n. Variable a will be equal to the number of attempts where k is not divisible to n O Repeats reading k from the terminal until successful and k is not divisible to n. Variable a counts how many times the user has entered a number divisible with n O Repeats reading k from the terminal if k is equal to 1 or k is divisible to n. Variable a counts how many times the user has entered a number divisible with n. O Repeats reading k from the terminal while successful and k is not divisible to n. Variable a counts how many times the user has entered a number divisible with n O Repeats reading k from the terminal. If k is divisible to n then variable a is incremented
