Question

我有以下功能

void f(double* arr) 
{ ... }

这是在C ++ 11中调用该函数的合理方法：f({10.0, 8.0});？感谢。

一种可能的解决方案是在void f(double* arr){ } void f_wrapper(std::vector<double> v){ f(v.data()); } int main(){ f_wrapper({1.,2.,3.}); }函数周围创建一个小包装器：

void f(const double* arr){

}

void f_wrapper(std::initializer_list<double> v){
    f(v.begin());
}

int main(){
   f_wrapper({1.,2.,3.});
}

或@（Kerrek SB）提到：

  Public Sub CheckAndPlay(ButtonName As String)
        Dim Target As Integer
        Dim Position As String = Space(256)
        Dim Length As String = Space(256)

        Target = Microsoft.VisualBasic.Right(ButtonName, 2)

        w = mciSendString("status " & Target & " position", Position, 256, 0)
        w = mciSendString("status " & Target & " length", Length, 256, 0)

        If Val(Position) = Val(Length) - 10 Or Val(Length) = Nothing Or Val(Position) = 0 Or Val(Position) = Nothing Then
            w = mciSendString("play " & ButtonName, Nothing, 0, 0)
        End If
    End Sub

c ++ 11初始化列表作为数组
