一些面试问题 [英] Some Interview Questions
问题描述
我今天在接受采访时遇到了这些问题：
1.使用C定义一个类。
2.编写一个执行垃圾收集的C函数：释放所有
分配回忆。
3.定义信号量。
4.什么是并行编程以及你会遇到什么样的问题
面对这种程序？
如果有人给出了第一个和第二个问题的答案，我会赞不绝口。
问候，
Matt

我今天在接受采访时遇到了这些问题：
1.用C语言定义一个班级。
C没有任何名为''class''的东西。
2.编写一个执行垃圾收集的C函数：释放所有已分配的内存。
不可能，除非你先写一个完整的内存管理
包装，跟踪所有的分配和删除。
3.定义信号。
C没有任何名为信号量的东西。
4.什么是并行编程以及你将遇到什么样的问题面对这种程序？
C没有任何名为''并行编程''的东西。
如果有人给第一个和
第二个问题。
这四个与C
语言有关的唯一问题是第二个，我回答了。

如果有人给出第一个答案，我会恭喜你。
第二个问题。
C没有课程。如果由你决定，你可以写：
#define class（1）
它是合法且可用的。这可能不是那个白痴面试官想要听到的东西，但是他没有白痴呢
本来就是他想要的。
＃2在标准C中是不可能的。任何垃圾收集都会将
限制为可能分配的项目的子集。
承担请注意，重新定义malloc是不允许的，
realloc，免费。只有C系统实现者可以获得这些
的东西。

出于好奇...所以你对这些问题的答案是什么？

I had these questions in an interview today:
1. Define a class using C.
2. Write a C functions that does garbage collection: frees all
allocated memories.
3. Define semaphore.
4. What is parallel programming and what kind of problems you will
face in this kind of programmings?
I will appriciate if someone gives some answers to the first and the
second questions.
Regards,
Matt

Not possible, unless you first write a complete memory management
wrapper that tracks all allocations and deletions.
3. Define semaphore.
C doesn''t have anything named a ''semaphore''.
4. What is parallel programming and what kind of problems you will
face in this kind of programmings?
C doesn''t have anything named ''parallel programming''.
I will appriciate if someone gives some answers to the first and the
second questions.
The only question of the four that has anything to do with the C
language is the second, and I answered it.

C does not have classes. If it is up to you, you could write:
#define class (1)
and it would be legitimate and usable. It may not be what the
idiot interviewer wanted to hear, but it he has not an idiot it
would have been what he did want.
#2 is not possible in standard C. Any garbage collection would
have to be limited to a subset of the possible allocated items.
Bear in mind that it is not permissable to redefine malloc,
realloc, free. Only the C system implementor can get at these
things.
