我有一个非常简单的例子

＃包括

int main() 
{
    std::cout << "Hello World!" << std::endl;
    return 0;
}

如果我在 Visual Studio Community 2019 上使用 Visual Studio Compiler 编译它，那么它会按预期工作。

但是，当我将编译器更改为与 Intel Parallel Studio 2020(19.1) 一起安装的 Intel C++ 时，它返回错误

如果我注释掉#include 和std::cout ~~，这基本上是一个空程序，那么它编译成功并且运行没有错误。
