C++函數重載無聊2

                  先看一段代碼ios

#include <iostream>

using namespace std;


template<typename elemType, size_t nSize>
class CRefAsParam

{
public:
    typedef elemType MyArray[nSize];
    static void RefAsParam(int p[]) {
       

    }
    static void RefAsParam(MyArray & aRR) {
        
    }
};

int main()

{
    typedef CRefAsParam<int, 10> MyType;
    MyType::MyArray a = {20, 30, 77};
    MyType::RefAsParam(a);
    return 0;
}
編譯就不能經過

編譯出錯:spa

/home/zhou/C++/Re/main.cpp:36: 錯誤:call of overloaded 'RefAsParam(CRefAsParam<int, 10u>::MyArray)' is ambiguouscode

ambiguous:adj. 模糊不清的;引發歧義的編譯器

在看編譯器的認識it

../Re/main.cpp:16:17: note: static void CRefAsParam<elemType, nSize>::RefAsParam(int*) [with elemType = int, unsigned int nSize = 10u]io

../Re/main.cpp:21:17: note: static void CRefAsParam<elemType, nSize>::RefAsParam(elemType (&)[nSize]) [with elemType = int, unsigned int nSize = 10u, CRefAsParam<elemType, nSize>::MyArray = int [10]]編譯

重載是在編譯期完成的(多態是在運行期完成的),編譯時,選擇時不能決定,因此報錯。class
