我只是想知道谁知道Windows、Mac OS X和Linux是由哪些编程语言组成的，以及操作系统的每个部分都使用了哪些语言(例如:内核、插件架构、GUI组件等)。
我假设每种都有多种语言，显然我知道Linux内核是用C编写的。
我完全猜测Mac OS X包含大量Objective-C代码，因为它是苹果从NeXT派生的语言。
Windows，我听说包含C, c++和英特尔汇编。Linux或Mac OS是否包含任何汇编代码?
还有，是否有像Ruby, Python之类的脚本语言被操作系统开发者用来编写部分操作系统的脚本?操作系统的哪些部分是用每种语言编写的?

作为Mac OS X核心的一个补充，Finder在Snow Leopard之前还没有用Objective-C编写。在Snow Leopard中，它是用Cocoa Objective-C编写的

Linux: C.组装中的部分部件。
[...] It's mostly in C, but most people wouldn't call what I write C. It uses every conceivable feature of the 386 I could find, as it was also a project to teach me about the 386. As already mentioned, it uses a MMU, for both paging (not to disk yet) and segmentation. It's the segmentation that makes it REALLY 386 dependent (every task has a 64Mb segment for code & data - max 64 tasks in 4Gb. Anybody who needs more than 64Mb/task - tough cookies). [...] Some of my "C"-files (specifically mm.c) are almost as much assembler as C. [...] Unlike minix, I also happen to LIKE interrupts, so interrupts are handled without trying to hide the reason behind them. (Source)
Mac OS X: Cocoa主要在Objective-C中。内核用C语言编写，部分部件用汇编。
Mac OS X, at the kernel layer, is mostly an older, free operating system called BSD (specifically, it’s Darwin, a sort of hybrid of BSD, Mach, and a few other things)... almost entirely C, with a bit of assembler thrown in. (Source) Much of Cocoa is implemented in Objective-C, an object-oriented language that is compiled to run at incredible speed, yet employes a truly dynamic runtime making it uniquely flexible. Because Objective-C is a superset of C, it is easy to mix C and even C++ into your Cocoa applications. (Source)
Windows: C, c++， c#。汇编程序中的部分部件。
对于Windows，我们几乎全部使用C、c++和c#。一些代码区域是手工调优/手工编写的汇编。(源)
Unix: C.汇编中的部分部件。(源)
你说得对，MacOSX的核心是Objective-C。
Windows C + +
Linux C
关于脚本语言，不，它们相当高级。
哇! !9年的问题，但我刚刚看到了一系列关于Windows命令行历史的内部文章，我认为其中一些可能与问题的Windows方面有关:
For those who care about such things: Many have asked whether Windows is written in C or C++. The answer is that - despite NT's Object-Based design - like most OS', Windows is almost entirely written in 'C'. Why? C++ introduces a cost in terms of memory footprint, and code execution overhead. Even today, the hidden costs of code written in C++ can be surprising, but back in the late 1990's, when memory cost ~$60/MB (yes … $60 per MEGABYTE!), the hidden memory cost of vtables etc. was significant. In addition, the cost of virtual-method call indirection and object-dereferencing could result in very significant performance & scale penalties for C++ code at that time. While one still needs to be careful, the performance overhead of modern C++ on modern computers is much less of a concern, and is often an acceptable trade-off considering its security, readability, and maintainability benefits ... which is why we're steadily upgrading the Console’s code to modern C++.
The Linux kernel is mostly written in C (and a bit of assembly language, I'd imagine), but some of the important userspace utilities (programs) are shell scripts written in the Bash scripting language. Beyond that, it's sort of hard to define "Linux" since you basically build a Linux system by picking bits and pieces you want and putting them together, and depending on what an individual Linux user wants, you can get pretty much any language involved. (As Paul said, Python and C++ play important roles)
