Question

There is an equivalent instruction to the JC instruction True False The following code will jump to the label named Target. mov eax-42 cmp car 26 ja Target True False What does the following code do? cmp al "0" jb ID1 cmp al "9" ja ID1 sub ax, ax ID1: Sets the ZF if the character in AL is a valid ASCII value corresponding to a decimal digit Sets the ZF flag only if the ASCII character is a character corresponding to 0 or 9 Sets the ZF if the value in AL is out of range Determines whether the character in AL is legal or not

Explanation / Answer

Question 1:-

True

There are two equalent instructions for JC. Those are JB (Jump if Below) and JNAE (Jump if Not Above Equal).These two works exactly same as JC(jump if carry). In Either of the cases microprocessor will set the condition CF=1.

Question 2:-

True.

Because the ja condition if always takes us to the destinaton mentioned , whenever the compare condition is satified which means the value must be above 1 then only it takes. If the cmp value is 0, then flag is set to 1 and the other set of instructions.

Question 3:-

Sets ZF if the value is out of range

Because whenever the value is goes out of the given range like < 0 or >9 only the ZF wil be set
