有没有办法将自动作为参数传递给C ++？ [英] Is there a way to pass auto as an argument in C++?

问题描述

有没有办法将auto作为参数传递给另一个函数？

Is there a way to pass auto as an argument to another function?

int function(auto data)
{
    //DOES something
}

推荐答案

如果您希望这意味着您可以将任何类型传递给函数，请将其设为模板：

If you want that to mean that you can pass any type to the function, make it a template:

template <typename T> int function(T data);

有一个C ++ 17的提议允许您使用的语法（因为C ++ 14已经对于通用lambda表达式），但它不是标准的。

There's a proposal for C++17 to allow the syntax you used (as C++14 already does for generic lambdas), but it's not standard yet.
