Question

The following data segment starts at memory address 0x4400 (hexadecimal)
.data
printString BYTE "Assembly is fun",0
moreBytes BYTE 28 DUP(0)
dateIssued DWORD ?
dueDate DWORD ?
elapsedTime WORD ?

What is the hexadecimal address of dueDate?

After the following MASM code is executed:
    mov    eax,52
    mov    ebx,17
    mov    ecx,23
    add    eax,ebx
    sub    eax,ecx

What is the value in the eax register (in decimal)?   
What is the value in the ebx register (in decimal)?   
What is the value in the ecx register (in decimal)?

Explanation / Answer

The address of the due date date =starting address+string bytes+more bytes+double word

=Starting address + 27(hex)

=0x4400+27

=0x4427

Address of the due date is 0x4427

Mov eax ,52//eax=52

Mov ebx,17//ebx=17

Mov ecx,23//ECX=23

Add eax,ebx//eax=eax+ebx

//Eax=52+17

//Eax=69

Sub eax,ecx

//Eax=eax-ecx

//69-23=46

Eax register value is70in decimal

Ebx value is 23 in decimal

Ecx register value is 35 in decimal
