C++ Exception Handling is centered around the three keywords: try, catch, and throw, the general purpose of which is to attempt to execute code and handle unexpected exceptional conditions, hence the name. This consists of utilizing a try block (with its attendant handlers). Here's a simple code snippet that should look familiar:try { if ( ! resourceAvail ) throw MyExceptionClass( "Resource Is Not Available" ); }catch(MyExceptionClass& myException) { // resource was not available, do something cleanup throw; }The code checks to see if a resource is available and if not, throws an exception. The handler for the MyExceptionClass presumably does something meaningful about the exceptional state. From this over-simplified example we can see a typical use of exceptions which is to prevent continued operation if the program cannot obtain the required resource. Another example of this use of exceptions is new(), which will throw the standard exception bad_alloc if the required amount of memory is not available. (Unless, of course, you've changed the new handler.) C++
