c++ - 为什么 C++ 不允许重新绑定(bind)引用？

Question

重新绑定(bind)引用有问题吗？我在谷歌上搜索了这个问题，但找不到这个问题的相关答案。是什么让 C++ 的设计者决定这样做？

Answer 1

Stroustrup 的 The Design & Evolution of C++回答大多数此类问题。在这种情况下，请参阅 §3.7 引用部分:

I had in the past been bitten by Algol68 references where r1=r2 can either assign through r1 to the object referred to or assign a new reference value to r1 (re-binding r1) depending on the type of r2. I wanted to avoid such problems in C++.
If you want to do more complicated pointer manipulation in C++, you can use pointers.
