Do the Even questions from section 4.4.5. Be careful with #8 part e! Explain why FALSE questions are FALSE.
(It wouldn't hurt if you studied the answers to the odd questions as well.)
In addition, do these problems:
Explain in general when a PTR operator is needed with an indirect operand. Give a specific example (other than the one in the book).
Describe in words what is happening in each of the following instructions.
TRUE | FALSE | Using a data item's label always results in that data item's offset within the data segment. |
---|---|---|
TRUE | FALSE | When this is done in the data portion of your program, you can initialize a 'pointer variable' to point to the data item. |
TRUE | FALSE | When this is done in the code portion of your program, the offset is automatically dereferenced to retrieve the value -- even when you don't use the [] to specify it. |
