We already know that we can create a lunar lander application of the pipe-and-filter architecture style from three independent Java classes: GeBurtenRate, Calc Values, and Display Values. As mentioned in class, they can be run as: java GetBurnRate | java Calc Values | java Display Values. Re-write Class Calc Values above using C++ (e. g., CalcNewValues. cpp), and run your application as: java GetBurnRate | CalcNewValues | java DisplayValues. Note that the second filter (i. e., CalcNewValues) is a C++ application. Your lunar lander application must behave in the same way as the original application.

Software bought revolutionary change making entrepreneurs fortunate enough to make money in less time with least effort and  

correct output. SDLC (Software development life cycle) is responsible for software’s reliability, performance, scalability,  

functionality and maintainability. Although all phases of SDLC have their own importance but Software architecture serves as  

the foundation for other phases of SDLC. Just like sketch of a building helps constructor to correctly construct the building,  

software architecture helps software developer to develop the software properly. There are various styles available for software  

architecture. In this paper, clear picture of all important software architecture styles are presented along with recent advancement  

in software architecture and design phases. It could be helpful for a software developer to select an appropriate style according to  

his/her project’s requirement. An architectural style must be chosen correctly to get its all benefits in the system. All the  

architectural styles are compared on the basis of various quality attributes. This paper also specifies the application area,

advantages and disadvantages of each architectural style.

Explanation:

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
