A megaproject is an extremely large-scale construction and investment project. [1] A more general definition is "Megaprojects are temporary endeavours (i.e. projects) characterised by: large investment commitment, vast complexity (especially in organisational terms), and long-lasting impact on the economy, the environment, and society".

In software engineering, a unity build (also known as unified build, jumbo build or blob build) is a method used in C and C++ software development to speed up the compilation of projects by combining multiple translation units into a single one, usually achieved by using include directives to bundle multiple source files into one larger file.
Because software, unlike a major civil engineering construction project, is often easy and cheap to change after it has been constructed, a piece of custom software that fails to deliver on its objectives may sometimes be modified over time in such a way that it later succeeds—and/or business processes or end-user mindsets may change to accommodate the software.
Concerns related to construction integration include planning the sequence in which components will be integrated, creating scaffolding to support interim versions of the software, determining the degree of testing and quality work performed on components before they are integrated, and determining points in the project at which interim ...
If it does not work, the only available function is the second test, and the resulting type of the expression is no. An ellipsis is used not only because it will accept any argument, but also because its conversion rank is lowest, so a call to the first function will be preferred if it is possible; this removes ambiguity.
C++ has more complicated rules about pointer assignments that add qualifiers as it allows the assignment of int ** to const int *const * but not the unsafe assignment to const int ** while C allows neither of those (although compilers will usually only emit a warning). C++ changes some C standard library functions to add additional overloaded ...
C only has limited amounts of information in header files, the most important being struct declarations and function prototypes. C++ stores its classes in header files and they not only expose their public variables and public functions (like C with its structs and function prototypes) but also their private functions. This forces unnecessary ...
Translation units define a scope, roughly file scope, and functioning similarly to module scope; in C terminology this is referred to as internal linkage, which is one of the two forms of linkage in C. Names (functions and variables) declared outside of a function block may be visible either only within a given translation unit, in which case they are said to have internal linkage – they are ...
