1. Describe in detail (more than ~100 words) what is the address of a variable. Give various types of examples.

2. What would print from the following segment of code. Explain each output and why it is what it is.

int x = 24;

int *intptr;

intptr = &x;

cout << x << endl;

cout << *intptr << endl;

cout << intptr << endl;

*intptr = 100;

cout << *intptr << endl;

cout << intptr << endl;

3. How can you use pointer to print the first element of an array? Give an example.

4. Explain the Program Output listed on page 507, Program9-7 of the text book. How does the pointer notation work with array name?

5. When you increment/decrement a pointer, are you changing the address or the element at the address? If it is the address, how does the program now how much to increment or decrement? Hint: Remember the use of sizeof function in earlier chapters.

6. Explain the difference between the following; assuming ptr1 and ptr2 are pointers to integers.

a. If (ptr1 < ptr2)

b. If (*ptr1 < *ptr2)

7. Read section 9.8 on pages 522-526 and answer the following:

a. Why do we need dynamic memory allocation?

b. What commands are used to allocate and release memory?

c. What is memory leak, and how do you prevent it?
