C language outsourcing development

The emergence of C language is directly related to the Unix operating system. In operating system development and various underlying developments, C language has an absolute advantage. This is also the reason why the C language in the United States and Europe ranks high in the programming language list. There are many software giants at the bottom level of the system. Their development teams continue to use the C language, and new employees have to use the C language.

The biggest advantage of C language is efficiency. It can be embedded in assembly development. The pointer directly uses the memory to ensure the data processing speed. In addition, language expansion is carried out on the processing of the underlying data, such as structure bit variables and byte alignment.

The most difficult point of C language to understand is the cross-line macro statement. Although pointers are difficult, they are often used. People can find examples to study and use, but the cross-line macro statements are rarely used. However, YYVigorous Software is researching and using a small This feature is exposed in the open source project. This small project is uthash. Uthash uses the C language to implement the definition, production and search of the hash data structure. There are many cross-line macros in uthash. If you make good use of the cross-line macro, it is equivalent to mastering the essence of the cross-line macro.

We have completed source code Secondary development for classic open-source projects Apache, wireshark and openssl，in the meanwhile, we communicated with the open-source teams of wireshark in English. Our products contain: the custom development of Apache streaming media server, and the development of the radius protocol cluster monitoring system based on wireshark And openssl extended function development.

The development environments of these three are different. Apache products are developed under Linux, wireshark products are developed by glibc under cygwin, and openssl is developed by VC under Windows.

 

C++ language outsourcing development

C++ has the advantages of the C language, and at the same time introduces object-oriented capabilities. Object-oriented solves the problem of upgrading the C language framework through encapsulation, inheritance and polymorphism, and then supports more application-level development problems.

Framework upgrade problem. Simply put, a feature set has multiple functions in the C language. To upgrade this feature set, you must re-encode the file where the function is located. Object-oriented uses virtual functions, and you can write new classes with inherited functions. , Let the new class implement the new function, so that both the old code and the new code can exist at the same time without affecting the overall function.

In addition, object-oriented can also solve the problem of insecurity of global variable data in C language, and the development characteristics of anthropomorphic form are easy for developers to accept.

However, because C++ introduced a virtual function table, C++ could not be selected when developing the system's low-level software. Ruiyingyuan Software encountered the problem of virtual function calls supported by the virtual function table causing the software to crash under a special stress environment.

We have completed source code Secondary development for classic open-source projects Darwin (Apple) and kaldi，in the meanwhile, we communicated with the open-source teams of kaldi in English. Our products contain: the native development of the full-platform speech recognition and the development of Darwin streaming media bugs and function enhancements.

 

Company info

YYVigorous software company is located in Zhengzhou, China and was established in 2008. It is an exceptional software outsourcing business with rich experience in full-stack development. We are particularly good at developing software in C language and C++ language.

YYVigorous software has worked with some successful and large-scale software platforms, such as streaming media platforms, China TravelSky’s airline ticketing platform, and primary and secondary education platforms. In addition to some large-scale projects, we also team up with many small open-source projects on www.codeproject.com.

During the development process, a large number of English materials have been translated into Chinese, and great amount of manual adjustments were made to the results of machine translation. Google may have collected our translation model and improved Google's translation effect.
