Replacing even array elements with zeros in assembler - c++

Question

There is the following problem:
I have an array, it is necessary to give its size and then in this array for each element that has an even value, assign the value zeros, and return the modified array.
There is my C++ code:
#include <iostream>
int main()
{
const int size = 10;
int arr[size] = { 1,2,3,4,5,6,7,8,9,10 };
for (int i = 0; i < size; i++)
{
if (arr[i] % 2 == 0)
arr[i] = 0;
}
for (int i = 0; i < size; i++)
{
std::cout << arr[i] << ' ';
}
system("pause");
return 0;
}
There is my nasm code:
%include "io64.inc"
section .text
global CMAIN
CMAIN:
mov DWORD size$[rbp], 10 ; size of array
; elements of array
mov DWORD arr$[rbp], 1
mov DWORD arr$[rbp+4], 2
mov DWORD arr$[rbp+8], 3
mov DWORD arr$[rbp+12], 4
mov DWORD arr$[rbp+16], 5
mov DWORD arr$[rbp+20], 6
mov DWORD arr$[rbp+24], 7
mov DWORD arr$[rbp+28], 8
mov DWORD arr$[rbp+32], 9
mov DWORD arr$[rbp+36], 10
mov DWORD i$4[rbp], 0
jmp SHORT $LN4#main
$LN2#main:
mov eax, DWORD i$4[rbp]
inc eax
mov DWORD i$4[rbp], eax
$LN4#main:
cmp DWORD i$4[rbp], 10
jge SHORT $LN3#main
movsxd rax, DWORD i$4[rbp]
mov eax, DWORD arr$[rbp+rax*4]
cdq
and eax, 1
xor eax, edx
sub eax, edx
test eax, eax
jne SHORT $LN8#main
movsxd rax, DWORD i$4[rbp]
mov DWORD arr$[rbp+rax*4], 0
$LN8#main:
jmp SHORT $LN2#main
$LN3#main:
mov DWORD i$5[rbp], 0
jmp SHORT $LN7#main
$LN5#main:
mov eax, DWORD i$5[rbp]
inc eax
mov DWORD i$5[rbp], eax
$LN7#main:
cmp DWORD i$5[rbp], 10
jge SHORT $LN6#main
$LN6#main:
mov edi, eax
lea rcx, QWORD [rbp-32]
mov eax, edi
lea rsp, QWORD [rbp+360]
pop rdi
pop rbp
ret
My question is: will this code work and how can it be optimized?
I just get errors like this:
C:\Users\79268\AppData\Local\Temp\SASM\program.asm:1: fatal: unable to open include file `io64.inc'
gcc.exe: error: C:\Users\79268\AppData\Local\Temp\SASM\program.o: No such file or directory
C:\Users\79268\AppData\Local\Temp\SASM\program.asm:6: error: comma, colon, decorator or end of line expected after operand
C:\Users\79268\AppData\Local\Temp\SASM\program.asm:9: error: comma, colon, decorator or end of line expected after operand
C:\Users\79268\AppData\Local\Temp\SASM\program.asm:10: error: comma, colon, decorator or end of line expected after operand
So, I install NASM and IDE SASM correctly...
I try to rewrite code and compile it in SASM:
section .data
arr dd 1, 2, 3, 4, 5, 6, 7, 8, 9,10
section .text
global CMAIN
CMAIN:
call calc
push arr
calc:
lea rsi, [arr]
mov rcx, [10]
mov rdi, rsi
xor rbx, rbx
##for:
lodsq
test al, 1
cmovz rax, rbx
stosq
loop ##for
ret
And I get the same error:
c:/program files (x86)/sasm/mingw64/bin/../lib/gcc/x86_64-w64
mingw32/4.8.1/../../../../x86_64-w64
mingw32/lib/../lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o):
crt0_c.c:(.text.startup+0x25): undefined reference to `WinMain'
Now I get the same error for updated code:
BITS 64
section .text
global _start
_start:
push arr
lea rsi, [arr]
mov rcx, [10]
mov rdi, rsi
xor rbx, rbx
##for:
lodsq
test al, 1
cmovz rax, rbx
stosq
loop ##for
ret
section .data
arr dd 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
$nasm -f elf *.asm; ld -m elf_i386 -s -o demo *.o
$demo

Any idea for fix and compile this programm? SASM is nit wirking on my machine, and a try to use this online NASM compilier: ASM Online compilier
