用汇编器中的零替换数组元素

Question

存在以下问题： 我有一个数组，有必要给出其大小，然后在此数组中，对于每个具有均值的元素，分配值零并返回修改的数组。

有我的C ++代码：

#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;
}

有我的NASM代码：

%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

我的问题是：该代码会起作用吗？

我只会得到这样的错误：

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:10: error: comma, colon, decorator or end of line expected after operand

因此，我正确安装了NASM和IDE SASM ...

我尝试重写代码并以SASM进行编译：

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

并且我遇到了相同的错误：

c:/program files (x86)/sasm/mingw64/bin/../lib/gcc/x86_64-w64
mingw32/4.8.1/../../../../x86_64-w64

现在，我对更新代码的错误遇到了相同的错误：

    lea rsi, [arr]

修复和编译此程序的想法吗？ SASM在我的机器上正在固定，并尝试使用此在线nasm编译器：
