Destructors and Exception Safety One beautiful thing about C++ exception handling is that the compiler calls destructors to clean up all variables that are running. try { if (badThingHappened) { throw std::runtime_error("Something Bad happened here"); } } catch(std::exception const& e) { std::cout << "Exception: " << e.what() << "\n"; } share|improve this answer answered Oct 15 French vs Italian resistance Most useful knowledge from the 30's to understand current state of computers & networking? These are arranged in a parent-child class hierarchy shown below: Here is the small description of each exception mentioned in the above hierarchy: Exception Description std::exception An exception and parent class Check This Out

Throw an "exception". defined (BOOST_NO_EXCEPTIONS) && ! To be portable, better use runtime_error. (And remember, just because a specification of your project says your code does not have to run on Linux, it does not mean it does There is nothing to stop you using std::exception and for simple application it may be all you need.

Std::runtime_error Example

This tutorial introduces C++ exception handling. It is used as a base class for several runtime error exceptions, and is defined as: 1
2
3
4
class runtime_error : public exception { public: explicit runtime_error (const string& what_arg); }; 1
2
3
4
5
This is also why there is no constructor taking std::string&&: it would have to copy the content anyway. Reimplemented from std::exception.

In all the examples above, I throw a "std::runtime_error".

Define New Exceptions You can define your own exceptions by inheriting and overriding exception class functionality. std::runtime_error An exception that theoretically can not be detected by reading the code. Runtime_error Was Not Declared In This Scope

  1. std::bad_cast This can be thrown by dynamic_cast.
  2. std::underflow_error This is thrown if a mathematical underflow occurs.
  3. Throwing Exceptions Exceptions can be thrown anywhere within a code block using throw statements.
  4. throw: A program throws an exception when a problem shows up.
  5. The operand of the throw statements determines a type for the exception and can be any expression and the type of the result of the expression determines the type of exception
  6. i.e.
  7. std::runtime_error on the other hand has valid constructors that accept a string as a message.
  8. This tutorial is intended for students and professionals who are already familiar with building C++ classes.

std::logic_error An exception that theoretically can be detected by reading the code. C++ Standard Exceptions C++ provides a list of standard exceptions defined in which we can use in our programs. class vr::CodeLineException< EXCEPTION > Namespaces namespace vr Macros #defineCODELINE_EXCEPTION(T, e)vrutils::CodeLineException( e, __FILE__, __LINE__ ) #defineCODELINE_RTEXCEPTION(what)vrutils::CodeLineException( std::runtime_error( what ), __FILE__, __LINE__ ) #defineEXCEPTION_IF_NULL(var)if ( var == NULL ) throw vrutils::CodeLineException( std::runtime_error( "NULL: this contact form Return an error code to the calling function.

Throwing some variant of std::exception is a much better idea, because std::exception can tell you exactly what went wrong.

The class inherits the what member function from exception. For example, the top-level code could move on to the next file, bring up an error dialog onscreen, send an email off to the author of the file, etc. Why my home PC wallpaper updates to my office wallpaper Schengen visa to Norway to visit my wife refused Unable to understand the details of step-down voltage regulator What are some C++ Catch Runtime Error If there is no chance of recovery than one of the standard exceptions is fine. –Loki Astari Oct 15 '09 at 3:48 1 Just as an aside: there is no

(Section 16.13 discusses class exception and its derived classes in detail.) A typical exception class that derives from the runtime_error C++ exception handling is built upon three keywords: try, catch, and throw. We use an object of this DivideByZeroException class in Fig. 16.2 to indicate when an attempt is made to divide by zero. 1 // Fig. 16.1: DivideByZeroException.h 2 // Class DivideByZeroException
