Exception handling (programming) In computer programming, several language mechanisms exist for exception handling. The term exception is typically used to denote a data structure storing information about an exceptional condition. One mechanism to transfer control, or raise an exception, is known as a throw; the exception is said to be thrown.
Exception handling. In computing and computer programming, exception handling is the process of responding to the occurrence of exceptions – anomalous or exceptional conditions requiring special processing – during the execution of a program. In general, an exception breaks the normal flow of execution and executes a pre-registered ...
Exception handling syntax. Exception handling syntax is the set of keywords and/or structures provided by a computer programming language to allow exception handling, which separates the handling of errors that arise during a program's operation from its ordinary processes.
Exception safety is the state of code working correctly when exceptions are thrown. [ 1] To aid in ensuring exception safety, C++ standard library developers have devised a set of exception safety levels, contractual guarantees of the behavior of a data structure's operations with regards to exceptions. Library implementers and clients can use ...
Microsoft Structured Exception Handling is the native exception handling mechanism for Windows and a forerunner technology to Vectored Exception Handling (VEH). [1] It features the finally mechanism not present in standard C++ exceptions (but present in most imperative languages introduced later). SEH is set up and handled separately for each ...
Run-time type information. 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 ...
In computer science, a call stack is a stack data structure that stores information about the active subroutines of a computer program. This type of stack is also known as an execution stack, program stack, control stack, run-time stack, or machine stack, and is often shortened to simply " the stack ". Although maintenance of the call stack is ...
C++ also contains the type conversion operators const_cast, static_cast, dynamic_cast, and reinterpret_cast. The formatting of these operators means that their precedence level is unimportant. Most of the operators available in C and C++ are also available in other C-family languages such as C#, D, Java, Perl, and PHP with the same precedence ...
