Question
What will be the value in EAX after the following lines execute?mov eax, 1002FFFFhinc ax
Solution
The value in EAX will be 10030000h after the following lines execute.
Here's the step-by-step explanation:
-
The
mov eax, 1002FFFFhinstruction moves the hexadecimal value 1002FFFFh into the EAX register. -
The
inc axinstruction increments the value in the AX register by 1. The AX register is the lower 16 bits of the EAX register. -
The value 1002FFFFh in binary is 0001 0000 0000 0010 1111 1111 1111 1111. When you increment the lower 16 bits (2FFFFh) by 1, it becomes 30000h (in hexadecimal) because 2FFFFh + 1 = 30000h.
-
Therefore, the final value in the EAX register is 10030000h.
