Question

Convert the C++ Source code into Assembly Language (MASM) Code:

int sum = 0, k = 1;

while ( k < = 20 )

{

if ( k % 2 == 0 )

sum + = k;

k++;

}

Answer 1

Here I am converting the lines of C++ code into masm.

mov dword ptr [sum], 0

mov dword ptr [k], 1

cmp dword ptr [k], 14h

jg main+63h

mov eax, dword ptr [k]

and eax, 80000001h

jns main+4Bh

dec eax

or eax, 0FFFFFFFEh

inc eax

test eax, eax

jne main+58h

mov eax, dword ptr[sum]

add eax, dword ptr [k]

mov dword ptr [sum], eax

mov eax, dword ptr [k]

add eax, 1

mov dword ptr [k], eax

jmp main+36h
