I\'ve been reading about strict aliasing quite a lot lately. The C/C++ standards say that the following code is invalid (undefined behavior to be correct), since the compiler might have the value of a
I\'ve read various previous questions about the use of reinterpret_cast, and I\'ve also read the relevant wording in the C++ standard.Essentially, what it comes down to is that the result of a pointer
Say I want to cast A* to char* and vice-versa, we have two choices (I mean, many of us think we\'ve two choices, because both seems to work! Hence the confusion!):
In the C++ Without Fear: A Beginner\'s Guide That Makes You Feel Smart book, and in chapter (8), it mentions the following about reinterpret_cast
Parent class: template <clas开发者_运维知识库s T> class Point { protected T x; T y; }; Derived class:
Although there was a lot of lines written on the topic of reinterpret_cast, and how bad it is, I\'m still puzzled with best way to avoid it, especially when dealing w开发者_Go百科ith functions like re
I have some C++ code I\'m trying to port to Java, that looks like this: struct foostruct { unsigned char aa : 3;
I have the following code for having a small class for storage. #include <iostream> template<typename T>
I\'ll start with the code: typedef std::vector<unsigned char> CharBuf; static const int RCV_BUF_SIZE = 1024;
My understanding is that C++ reinterpret_cast and C pointer cast is a just a compile-time functionality and that i开发者_开发问答t has no performance cost at all.
