我使用的是 Visual Studio 2019 免费版。我创建了一个空白项目，然后添加了 .masm(.targets, .props) 的依赖项。但是，我收到一个错误，不确定是我的 Visual Studio 设置还是其他原因。
我正在学习汇编程序类，需要修改我们书中的一个示例以执行更多操作，但首先我希望原始代码能够工作。因此，我输入了书中的代码，但收到了大量关于 io.h 的错误，我不知道该怎么办。我希望有人能指出我做错了什么。我在 Google 上找到了一篇文章解决了这个问题，但没有解决问题，io.h 中的另一篇建议的 C++ 注释是问题所在，但我似乎无法删除它们并将文件保存回去。
这是我的代码：
.586
.MODEL FLAT
INCLUDE io.h ; header file for input/output
.STACK 4096
.DATA
number1 DWORD ?
number2 DWORD ?
prompt1 BYTE "Enter First Number", 0
prompt2 BYTE "Enter Second Number", 0
string BYTE 40 DUP (?)
resultLb1 BYTE "The Sum Is", 0
sum BYTE 11 DUP (?), 0
.CODE
_MainProc PROC
input prompt1, string, 40 ; read ASCII Characters
atod string ; convert to integer
mov number1, eax ; store in memory
input prompt2, string, 40
atod string
mov number2, eax
mov eax, number1
add eax, number2
dtoa sum, eax
output resultLb1, sum
mov eax, 0
ret
_MainProc ENDP
END ; end of source code
