The constructor is a special function. There is also a destructor in C++.
The answer to this question is (B) Executive summary. An executive summary should be written last since its purpose is to summarize the content of the document, in this case, the business plan. Thus, the readers can use an executive summary to get an overview of the document without having to read the business plan in its entirety.
Answer:
Pointer or cursor.
Explanation:
A GUI or graphical user interface operating system is a system software used to manage the activities of the application softwares, provides utilities to maintain system performance and provides the user with graphic icons to make system interaction easy.
Unlike command line interface OS, command does not need to be typed to its interface, but a pointer representing a pointing device like a mouse is used to select and run programs.
In my opinion would also qualify in most cases. I consider utility software like CCleaner, Antivirus software, and other system clean-up products, applications. I think the author of the question is trying to distinguish between utility software that does work on the system and software geared to "real world" tasks like browsing the web or creating documents.
PeNgUiNz RuLe has an even wider definition than I do, but I see some merit in what he is saying. OS's are applications that allow you to manage files and work with other applications. Theoretically, compiler could be a standalone application. You could open it and feed it a text file with code and it could kick out an executable file. More often than not these days compilers are parts of bigger applications called IDEs (Integrated Development Environments). A good example of this in Windows is Microsoft Visual Studio Express. You can write code in it and then use the compiler to create an executable file.
