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 *`. It can be made legal by casting `low` and `high` to numbers, performing the operation, then casting to a pointer.
|
|
```c
|
|
middle = (int*) (((long) low + (long) high) / 2);
|
|
