Deck 8: Advanced Procedures Assessment

Question 1

Arrays are usually passed by reference when calling subroutines.

Answer 1

True

Question 2

The assembler checks the pointer type used with the ADDR operator against the pointer type declared in the PROC directive.For example,it prevents a pointer to DWORD from being passed to a procedure expecting an pointer to BYTE.

Answer 2

False

Question 3

In 32-bit programs,ADDR and OFFSET return the same value.

Answer 3

True

Question 4

Stack parameters are usually expressed as positive offsets from ESP.

Question 5

An indirect operand such as [eax + edi] can be passed to the INVOKE directive.

Question 6

When a 32-bit mode prgram needs to pass a 64-bit integer argument to a subroutine on the stack,you should push the low-order doubleword of the argument first,followed by the high-order doubleword.

Question 7

The CALL instruction can only have a single operand.

Question 8

The following is a valid LOCAL declaration:
LOCAL index:DWORD

Question 9

In assembly language,a variable declared using the LOCAL directive in one procedure can be read by code in another procedure.

Question 10

The following is a valid LOCAL declaration:
LOCAL pArray:DWORD PTR

Question 11

The C calling convention is used by the Irvine32 library.

Question 12

When a subroutine argument is passed by value,the calling program pushes the argument's address on the stack.

Question 13

Local variables are stored on the runtime stack,at a higher address than the stack pointer.

Question 14

The following is a valid LOCAL declaration:
LOCAL LastName:BYTE(25)

Question 15

The C calling convention requires the calling program to reset the stack pointer after the subroutine has returned.
