爲什麼不用VC++ 2008Express編譯這個程序？

該程序編譯並在TC++ 3.0上運行。爲什麼不用VC++ 2008Express編譯這個程序？

#include <iostream> 

using namespace std; 

class MyClass 
{ 
private: 
    class MyNestedClass 
    { 
    private: 
     int myInteger; 

    public: 
     MyNestedClass(int a) 
     { 
      myInteger = a; 
     } 
     void Show() 
     { 
      cout<<myInteger; 
     } 
    }; 
}; 

int main() 
{ 
    MyClass::MyNestedClass myNestedClassObject(100); 

    myNestedClassObject.Show(); 
}

如果你指出第39行是... –

可能是因爲你編譯爲'c'而不是'C++'？ – Nim

請注意，Turbo C++ 3.0已有20年曆史。將會有很多代碼被現代編譯器接受（現代編譯器可以接受的代碼更多，但Turbo C++不會）。 –

這是一個C++程序，但你給你的源文件的擴展名爲.c。

默認情況下，Visual C++編譯器將.c文件編譯爲C.使用.cpp擴展名或使用/ TP標記進行編譯以將源代碼編譯爲C++。

但是，即使您將源代碼編譯爲C++，該程序仍然無效。 MyNestedClass是MyClass的私人成員類型，因此您無法在main()中構建它的實例。

+1非常有趣。實際的C++編譯器是否做出這個假設或者Visual Studio（然後通過編譯器選項傳遞它的假設）？ – JaredPar

@JaredPar：這是一個編譯器功能。另請參閱[/ Tc，/ Tp，/ TC，/ TP]（http://msdn.microsoft.com/zh-cn/library/032xwy55.aspx） –

@JaredPar如果您在項目的屬性中可以對其進行全局更改想要（即總是使用C++編譯器，即使是以.c結尾的文件） - 至少對於專業版本的VS. – Voo

爲什麼不用VC++ 2008Express編譯這個程序？
