可以在C ++ 11中将'auto'关键字用作存储类说明符吗? [英] Can the 'auto' keyword be used as a storage class specifier in C++11?

问题描述

auto关键字可以用作C ++ 11中的存储类说明符吗?

Can the auto keyword be used as a storage class specifier in C++11?

以下代码在C ++ 11中合法吗?

Is the following code legal in C++11?

int main() {
   auto int x;
}

推荐答案

C ++ 11中的代码格式不正确. C ++ 11中的auto将用于从其初始值设定项推导变量的类型，并且不能将其用作存储类说明符.

No the code is ill-formed in C++11. auto in C++11 would be used to deduce the type of a variable from its initializer and it can't be used as a storage class specifier.

正确用法

int main()
{
   auto x = 12; // x is an int
   auto y = 12.3; // y is a double
}
