What will be the value of AX (in Hexadecimal) after execution of the following instructions:
MOV CX,3
MOV AX,0018H
MOV BL,2
BACK: DIV BL
MUL CL
LOOP BACK
With LOOP instruction the jump gets executed when:
Select one:
a. When CX reaches zero
b. When DI reaches zero
c. When SI reaches zero
d. None of the options given here
e. When zero flag is set
Consider the following instructions
for i - x to x+3 do
v - i
for j - 1 to y do
V - v*i
end for
print v
end for
[NOTE:The statement i+ X replaces the old value of the variable i with the result of evaluating the expression x. For example, if i initially contains 7 then
the statement i +x+1 results in i containing 8.]
Which of the following cannot be produced by the instructions for any value of x?
