Because name of arrays represent just a pointer to the beginning of the array, we have some limitations or “problems.”

• No Array Out of Bounds Checking is allowed.

For example:

int i a [2] = {0,1};
printf (“%d”, ia [2]);

The above code will lead to segment fault, because you are trying to look at an area of memory not inside the array memory allocation.

• • Array size must be constant or known at compile – time.
• • Array cannot be copied or compared, because they are pointers.
• • Array index type must be integral.
• • Another limitation comes with arrays being passed into functions. For example:

void func (int ia [])
void func (int * ia)

Both ate the same declaration. But why would this cause problems? Because only the pointer to the array is passed in, not the whole array. So, what if you mistakenly did a size of (ia) inside func? Instead of returning the size of the whole array, it would only return the size of a single element in the array.
