Question

我正在尝试将Visual Studio 2010设置为执行普通的旧ANSI编译，而不使用任何类型的Microsoft扩展。

我从一个空的项目模板开始，因为2010年似乎没有一个普通的ANSI项目模板了。

然后我设置

属性 - ＆gt;配置属性 - ＆gt; C / C ++ - ＆gt;语言 - ＆gt;禁用扩展名=是（/ Za）

这是我的代码：

#include <iostream>

int main( int argc, const char* argv[] )
{
  std::cout << "Hello World!";
  return 0;
}

以下是错误：

我如何才能获得最基本的C ++代码以便干净地编译？

Answer 1

如果define wchar_t as native type，则错误消失。

Answer 2

如果我将代码复制到文件test.cpp中，然后发出命令

cl /Za /EHsc test.cpp

然后它在我安装visual c ++ express 2010时没有任何警告或错误就干净地编译。/ EHsc是正确处理异常所必需的，我不明白为什么它不是默认的。

这与你在做什么不同？

为什么这段代码不能在Visual Studio 2010中编译和运行？
