The assert macro implements runtime assertion. If the expression within it is false, the macro will print a message to stderr and call abort(), defined in stdlib.h.The message includes the source filename and the source line number from the macros __FILE__ and __LINE__, respectively. [2]
When an assertion failure occurs, the programmer is immediately notified of the problem. Many assertion implementations will also halt the program's execution: this is useful, since if the program continued to run after an assertion violation occurred, it might corrupt its state and make the cause of the problem more difficult to locate.
Microsoft Visual C++ (MSVC) is a compiler for the C, C++, C++/CLI and C++/CX programming languages by Microsoft. MSVC is proprietary software ; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms.
It's delivered as a standalone application that runs from the command line, or as a plug-in to Eclipse or Microsoft Visual studio. Various modules in the set assist software developers in performing static and dynamic analysis, creating, executing and maintaining unit tests, measuring code coverage and other software metrics, and executing ...
The Metacode extension to C++ (Vandevoorde 2003) [1] was an early experimental system to allow compile-time function evaluation (CTFE) and code injection as an improved syntax for C++ template metaprogramming. In earlier versions of C++, template metaprogramming is often used to compute values at compile time, such as:
A failed bounds check usually results in the generation of some sort of exception signal. As performing bounds checking during each use can be time-consuming, it is not always done. Bounds-checking elimination is a compiler optimization technique that eliminates unneeded bounds checking.
A newer language construct (since C++11 and C23), constexpr allows for declaring a compile-time constant value that need not consume runtime memory. [20] Inline function. For a long time, a function-like macro was the only way to define function-like behavior that did not incur runtime function call overhead.
In computer programming, run-time type information or run-time type identification (RTTI) [1] is a feature of some programming languages (such as C++, [2] Object Pascal, and Ada [3]) that exposes information about an object's data type at runtime. Run-time type information may be available for all types or only to types that explicitly have it ...
