Question

Given the macro definition and global declarations shown in the image below, provide answers to the following questions:

A. After the statement "quiz4 x,4" executes, x contains
B. The statement "quiz4 6,4" will produce an error when the macro is invoked. (Enter true or false)
C. Suppose that the following code executes:
mov ebx, 3
mov ecx, 12
mov edx, ecx
quiz4 ecx, ebx
Upon completion, edx will contain_______
Hint: Think carefully, part C may be more difficult than it seems.
quiz4 MACRO p,q
LOCAL here
push eax
push ecx
mov eax, p
mov ecx, q
here: mul P
loop here
mov p, eax
pop ecx
pop eax
ENDM .
data
x DWORD 3
y DWORD 3

Answer 1

A. 243

B. True

C. 0

Step-by-step explanation:

Macro instruction is a line of coding used in computer programming. The line coding results in one or more coding in computer program and sets variable for using other statements. Macros allows to reuse code. Macro has two parts beginning and end. After the execution of statement of quiz4 x, 4 the macro x will contain 243. When the macro is invoked the statement will result in an error. When the macro codes are executed the edx will contain 0. Edx serve as a macro assembler.
