Exceptions
The class exception provides a common interface to signal for error conditions through the throw expression.
Exception categories
Several convenience classes are predefined 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.
Error numbers
Several macros are available, that provide POSIX error number support. An errno variable is also supported, a separate value is given to each thread.
Assert
assert macro aborts the program if the user-specified condition is not true.
static_assert function renders the program ill-formed if the user-specified condition is not true Template:mark c++11 feature.
