|
|
|
|
|
1. a. Declare a pointer variable p and initialize it to point to a char variable named ch. |
|
|
|
|
|
|
|
|
b. Declare a pointer variable q and initialize it to point to the first element of a long array named arr. |
|
|
|
|
|
|
|
|
c. Declare a pointer variable r and initialize it to point to a variable named box of type |
|
|
|
|
|
|
|
|
struct BoxType
{
int length;
int width;
int height;
}; |
|
|
|
|
|
|
|
|
2. Using the variables p, q, and r of Exercise 1, write code to do the following: |
|
|
|
|
|
|
|
|
a. Store @ into the variable pointed to by p. |
|
|
|
|
|
|
|
|
b. Store 959263 into the first element of the array pointed to by q. |
|
|
|
|
|
|
|
|
c. Store a length, width, and height of 12, 14, and 5 into the variable pointed to by r. |
|

3. Write a Boolean value-returning function that takes two pointer variablesptr1 and ptr2as parameters. Both variables point to float data. The function should return TRUE if the two pointers point to the same variable, and FALSE otherwise. |
