Partially-filled Arrays
Write the function rindby() which stands for remove mark>if not divisiby by. The function removes all elements from the array that are not evenly divisible by the argument n. You can find out if a number is evenly divisible by n using the remainder operator: % (there will be nothing left over).
The function returns the number of items removed or -1 if the array was originally empty.
The function takes 3 arguments:
the array of int that may be modified.
the size of the array (use size_t as the type)
the int n used to check for divisibility
Here are two short examples:
int a[] = {2, 3, 4, 5, 6};
size_t size = 5;
int removed = rindby(a, size, 2);
// removed->2, a = [2, 4, 6], size = 3
size = 0;
removed = rindby(a, size, 3);
// removed-> -1, no change otherwise
In the first case, the numbers 3 and 5 are removed because they are not divisible by 2. Only the numbers that are divisible by 2 are left in the array.
In the second, size has been set to , so the input array is empty and the function returns - 1.
