你什么时候会使用一个数组而不是一个向量/字符串？ [英] When would you use an array rather than a vector/string?

问题描述

我是一个初学者的C ++程序员，所以我一直使用数组而不是向量（这个似乎是做事情的一般方式，然后转移到载体稍后）。据悉

I'm a beginner C++ programmer and so I've learnt using arrays rather than vectors (this seems to be the general way to do things, then move on to vectors later on).

我注意到有很多对SO答案建议使用超过阵列载体和字符串在字符数组。看来，这是正确的方法在C + + code。

I've noticed that a lot of answers on SO suggest using vectors over arrays, and strings over char arrays. It seems that this is the "proper" way to code in C++.

这一切都这样说，当它仍然是值得使用的是经典阵列/炭*（如果有的话）？

That all being said, when is it still worth using a classic array/char* (if ever)?

推荐答案

在写code，如果你的目标特殊平台（嵌入式，游戏机等）应在其他项目中使用，特别是在STL可能​​不是present。

When writing code that should used in other projects, in particular if you target special platforms (embedded, game consoles, etc.) where STL might not be present.

旧的项目或有特殊要求的项目，可能不希望对STL库引入的依赖关系。这取决于阵列，烧焦*或因为它是语言的一部分任何将与任何兼容的接口。但是STL不保证为present在所有构建环境。

Old projects or projects with special requirements might not want to introduce dependencies on STL libraries. An interface depending on arrays, char* or whatever will be compatible with anything since it's part of the language. STL however is not guaranteed to be present in all build environments.
