  • You have come a long way since the start of this book. In this, the final module, you will examine several important, advanced C++ topics, including exception handling, templates, dynamic allocation, and namespaces. Runtime type ID and the casting operators are also covered. Keep in mind that C++ is a large, sophisticated, professional programming language, and it is not possible to cover every advanced feature, specialized technique, or programming nuance in this beginner’s guide.

  • Patch by Exception is a jumpered Block cabling solution with the flexibility of overriding jumpers with the simple use of a Patch Cord. This effectively provides the simplicity of an RJ solution without the need for patch management, eliminating messy wiring. Clipsal 3104 Series Patch by Exception modules guarantee excellent high output transmission performance.

  • An exception is an error that occurs at runtime. Using C++’s exception handling subsystem, you can, in a structured and controlled manner, handle runtime errors. When exception handling is employed, your program automatically invokes an error-handling routine when an exception occurs. The principal advantage of exception handling is that it automates much of the error-handling code that previously had to be entered “by hand” into any large program.

  • Exception Handling typically throws any number of exception values, of differing types ,Of course only one exception thrown Since throw statement ends try-block. But different types can be thrown, Each catch block only catches "one type".Typical to place many catch-blocks after each try-block.

  • Exception handling is the process of responding to the occurrence, during computation, of exceptions – anomalous or exceptional events requiring special processing – often changing the normal flow of program execution. It is provided by specialized programming language constructs or computer hardware mechanisms.

  • With exceptions, the error handling interface is much easier. The C++ throw command creates an expection that's handled by the catch block. The nice thing only the functions that does the throw and the one that catches it need to worry about the exception. All the other functions on the call stack don't have to worry about problems and don't have to pass error codes up the call stack.
