1. Suppose that the following declarations are in effect:.... a. 14 b. 34 c. 4 d. true e. false

2. 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?

middle = (low + high) / 2

The above statement is illegal because you can't add an int * to an int *. It can be made legal by casting low and high to numbers, performing the operation, then casting to a pointer.

middle = (int*) (((long) low + (long) high) / 2);
