This article mainly introduces "why there is a pairwise overloaded allocation and release function in C++". In daily operation, I believe that many people have doubts about why paired overloaded allocation and release function is needed in C++. The editor consulted all kinds of data and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the question of "why there is a pairwise overloaded allocation and release function in C++". Next, please follow the editor to study!

R.15: should overload allocation and release functions in pairs

Reason (reason)

Otherwise, mismatched operations and confusion will occur.

Example (sample)

Class X {

/ /...

Void* operator new (size_t s)

Void operator delete (void*)

/ /...

}; Note (note)

If you need memory that will not be freed, use = delete to disable the release operation. Don't let it go undefined.

Enforcement (implementation recommendations)

Tags are not overloaded in pairs.

At this point, the study of "why there is a paired overload allocation and release function in C++" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
