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?

Windows: c++，内核是C语言 Mac: Objective C，内核是C (IO PnP子系统是嵌入式c++) Linux:大多数东西都是C语言，许多用户应用程序是Python语言，KDE都是c++语言
所有内核都将使用一些汇编代码。

Windows:主要是C和c++，还有一些c#
请参阅标题下的一个操作系统在多个平台上运行，其中说明:
Most of the source code for Windows NT is written in C or C++.
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)
