为什么它不是构造函数的好代码 [英] Why it is not good code for constructor
问题描述
大家好，
以下是Dr. Dobb C ++的样本。在分析中，代码不好
以下。
但我不认为代码不好，
1.如果在新的int []中抛出bad_alloc，我们只是抓住它并写下
一些日志;
2.如果B中有任何异常''的构造函数，我们也将在
catch块中，我们也可以写一些日志。
为什么代码不好？任何评论？
（我不同意有资源泄漏，因为如果我们在new int []中遇到
bad_alloc，就没有内存完全分配，所以没有内存/资源泄漏的根据。

Hello everyone,
Here is a sample from Dr. Dobb C++. In the analysis, the code is bad
below.
But I do not think the code is bad,
1. if bad_alloc is thrown in new int[], we just catch it and write
some log;
2. if there are any exception in B''s constructor, we will also be in
catch block and we could also write some log.
Why it is bad code? Any comments?
(I do not agree that there is resource leak, since if we met with
bad_alloc in new int[], there is no memory allocated at all, so no
root of memory/resource leak).

为什么代码不好？有什么意见吗？
（我不同意资源泄漏，因为如果我们在新的int []中遇到了bad_alloc，根本没有分配内存，所以没有root <内存/资源泄漏）。
