1. Operating system
Microsoft Windows：Assembly -> C -> C++
Note: Once in the smartphone operating system (Windows Mobile) to consider mixing the program written in C#, such as soft keyboard, the results are too slow to write out the program, it is impossible to merge with other modules, and finally back to C++ rewrite.
I believe many friends know Windows Vista, the system development early Bill Gates wanted to write all in C#, but finally because of the slow implementation and give up, the results of the previous countless software engineers work day and night results overnight was declared null and void.

Opera: C++ (more popular on cell phones)
Opera Mini: Opera Mini (2007) has a very funny architecture, and is indeed using both C++ and Java. The browser is split in two parts, an ultra thin (less than The first uses Java and receives the page under the OBML format, the latter reuses The first uses Java and receives the page under the OBML format, the latter reuses classical Opera (C++) rendering engine plus Opera’s Small Screen Rendering, on the server. This allows Opera to penetrate various J2ME-enabled portable devices, such as phones, while preserving excellent response time. execution.

facebook: C++ and PHP
This line is only about facebook, not its plugins. Plugins can be developed in many different technologies, thanks to facebook’s ORB/application server Thrift contains a compiler coded in C++. facebook people write about Thrift: “The multi-language code generation is well suited for search because it allows for application development in an The multi-language code generation is well suited for search because it allows for application development in an efficient server side language (C++) and allows the Facebook PHP-based web application to make calls to the search service using Thrift PHP libraries.” Aside the use of C++, facebook has adopted a LAMP architecture.

The C++ language is close to the bottom of the system and has the fastest execution speed. For example, your two friends and you respectively play with VB, Java, and C++ written “run kart”, you play the game written in C++ has been running and playing the end, found that your two friends have not started to run it, that is quite a card ah.
