相关疑难解决方法(0)

我正在尝试根据我的需要调整在可变参数模板函数中避免使用struct的解决方案.但是,我无法理解G ++的行为.考虑以下功能:

 template <typename T, unsigned Size>
 int nextline(const typename std::array<T, Size> ar) {
    return 0;
 }

然后是电话

 nextline(std::array<int, 2> { 1,0 });

与GCC抱怨不符

eslong.cpp: In function ‘int main()’:
eslong.cpp:10:38: error: no matching function for call to ‘nextline(std::array<int, 2ul>)’
   nextline(std::array<int, 2> { 1,0 });
