Suppose that `high`, `low`, and `middle` are all pointer variables of the same type, and the `low` and `high` point to elements of an array. Why is the following statement illegal, and how could it be fixed? +```c +middle = (low + high) / 2 +``` +The above statement is illegal because you can't add an `int *` to an `int *`.
