iterating in a array in C

Question

Hey I have something of this type

eph_t *a;

The type is eph_t as you can see. Its an array in C but I do not know the size of the array nor do I know what is the end element of the array. Is there a way, I can go through the whole array because I want to assign the values of every element in an array to something.

What can be my options to consider? If you could not understand something in the question just comment so that I can inform you.

Answer 1

If you do not know the size of the array then it is unsafe to iterate over it. Any time that you attempt to read elements beyond the last one you will get undefined behaviour. There is nothing safe you can do unless you know the size of the array.
