Module12 Exceptions, Templates, and Other Advanced Topics

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.
