Q1)

Suppose that you are given the following program. Inside someProcedure, what numerical operand should be used with the RET instruction? .data x DWORD 153461 y BYTE 37 z BYTE 90 .code main PROC push x push y push z call someProcedure inc EAX mov EBX, z xor EAX, EBX exit main ENDP END MAIN

(Answer is 6, could you explain why?)

Q2)

Suppose that you are given the following program (with memory addresses shown on the left). What hexadecimal value does EIP hold immediately after "inc EAX" has executed? .data 0x100 x DWORD 153461 0x104 y BYTE 37 0x105 z BYTE 90 .code main PROC 0x12 push x 0x17 mov AH, y 0x1C mov AL, z 0x21 call someProcedure 0x26 inc EAX 0x2B mov EBX, z 0x30 xor EAX, EBX 0x35 exit main ENDP END MAIN

(Answer is 0x2B, could you explain why?)
