+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?
+```c
+middle = (low + high) / 2
+```
+The above statement is illegal because you can't add an `int *` to an `int *`. The below operation is legal because you can perform pointer subtraction, and because `low` is defined on the left hand side of the equation, then adding a long to a pointer is valid.
+```c
+middle = low + (high - low) / 2;
+```
+
+3. What will be the contents of the `a` array after the following statements are executed?
+```c
+{10, 9, 8, 7, 6, 5, 4, 3, 2, 1}
