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}
|
||
|
|
```
