英文:
What is absent in go that C++ has?
问题
Go语言旨在成为一种简单的语言，大约有25个关键字。因为它很简单，我想知道与其他语言（如C++或C#，在我看来比C++更复杂）相比，它有什么不同。
我理解它之所以简单是因为它有较少的关键字和其他东西，但我不了解这门语言，所以它为了这个决定而做出了什么妥协或放弃了什么？
英文:
Go is meant to be a simple language and there is about 25keywords. Because it is simple i was wondering what does it not have compared to other language like C++ or C# (which IMO is more complex than C++)
I understand its simple bc it has less keywords and other things but i dont know the langauge so what did it have to tradeoff or leave out because of that decision?

正如其他人所评论的，关键字的数量并不是衡量简单性的指标，但你是对的，Go确实很简单。我不了解C#，但以下是一些Go中没有的一些基本C++特性：
- 泛型（模板）。关于如何在Go中支持泛型已经进行了很长时间的讨论。它们可能会在未来的某个时候出现，但现在还没有。
- 继承。Go的类型模型不像那样工作。这意味着没有重载，没有受保护的字段，没有多态等。
- 异常处理。Panic和recover可以实现类似的功能，但它不是异常处理。
- 构造函数和析构函数。类型只有初始值，仅此而已。
- C宏。
我可能漏掉了一些东西。
编辑：我忘记了指针算术。
英文:
As others commented, number of keywords is not a metric for simplicity, but you're right that Go is simple. I don't know C#, but here are some essential C++ features not available in Go:
- Generics (templates). There's been a long discussion about how to have support for generics in Go. They may come someday, but not yet.
- Inheritance. Go's typing model just doesn't work like that. That means there's no overloading, no protected fields, no polymorphism, etc.
- Exception handling. Panic and recover covers that, but it's not exception handling.
- Constructors and destructors. Types have initial values and that's all.
- C macros.
I may be missing something.
EDIT: I missed pointer arithmetic.
