问题描述
What C++ idioms should C++ programmers know?
By C++ idioms, I mean design patterns or way of doing certain things that are only applicable for C++ or more applicable for C++ than most other languages.
Why one should use the idioms, and what do the idioms accomplish?
推荐答案
Here is one list. If I had to pick a couple I might go with the Curiously Recurring Template Pattern or Virtual Contstructors.
其他推荐答案
By far the single most important "pattern" to learn and know that's (nearly) unique to C++ is RAII (Resource Acquisition Is Initialization).
Edit: (To answer extra question edited into the question). You use RAII primarily to (semi-)automate resource management. The most obvious use is freeing resources owned by objects when the owning objects go out of scope, such as freeing memory or closing files.
