Exception handling
The header <exception> provide several classes and functions related to exception handling in C++ programs.
Exception categories
Several convenience classes are predefined in the header <stdexcept> to report particular error conditions. These classes can be divided into two categories: logic errors and runtime errors. Logic errors are a consequence of faulty logic within the program and may be preventable. Runtime errors are due to events beyond the scope of the program and can not be easily predicted.
| Defined in header
<stdexcept> | |
| exception class to indicate violations of logical preconditions or class invariants (class) | |
| exception class to report invalid arguments (class) | |
| exception class to report domain errors (class) | |
| exception class to report attempts to exceed maximum allowed size (class) | |
| exception class to report arguments outside of expected range (class) | |
| exception class to indicate conditions only detectable at run time (class) | |
| exception class to report range errors in internal computations (class) | |
| exception class to report arithmetic overflows (class) | |
| exception class to report arithmetic underflows (class) | |
Error numbers
| Defined in header
<cerrno> |
Assertions
Assertions help to implement checking of preconditions in programs.
| Defined in header
<cassert> | |
| aborts the program if the user-specified condition is not Template:cpp. May be disabled for release builds (function macro) | |
System error
The header <system_error> defines types and functions used to report error conditions originating from the operating system, streams I/O, Template:cpp, or other low-level APIs.
