为什么C ++有一个“;”后的类声明 [英] Why does C++ have a ";" after a class declaration

问题描述

我开始学习C ++，出于好奇，为什么C ++要求你放一个;在类声明结束时
例如：

I'm starting to learn C++ and just out of curiosity, why does C++ require you to put a ";" at the end of the class declaration for example:

class A
{
   /*...*/
};

在Java等语言中，它用于表示语句的结尾。

In languages like java, it's used to signify an end of a statement.

int i(5);

和上面的类关于C ++中的分号编译器将类视为语句还是对其有不同的解释？

and the class above with regards to the semi-colon in C++? Does the compiler treat the class as a statement or does it have a different interpretation for it?

推荐答案

，因为您也可以在声明中定义变量：

because you can also define variables in the declaration:

class A {
        ...
} x, y, z;

在分号中结束类声明基本上明确说明我们不是 声明此类型的任何变量。

Ending class declarations in a semicolon is basically saying explicitly that we are not declaring any variables of this type.
