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?

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。

Windows:主要是C和c++,还有一些c#

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)

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++.
