What is a 'large number, represented as an array of decimal digits'. Is it the sum of the numbers in the array?

Write a C function that returns 1 if a large number, represented as an array of decimal digits, is exactly divisibly by 7, otherwise 0. The number has n decimal digits.

int div7(int number[], int n)

That is the question.

Does he mean that I have to add the numbers in the array which is the 'large number'?

But it is also an int, so it wouldn't have decimal places?

No, you shouldn't sum the numbers. The number 279 would be represented as {2,7,9}, for example. 279 is divisible by 7, but 2+7+9 isn't.
