Error recovery is a fundamental concern for every program you write, and it’s especially important in C++, in which one of the goals is to create program components for others to use. To create a robust system, each component must be robust.
The goals for exception handling in C++ are to simplify the creation of large, reliable programs using less code than currently possible, with more confidence that your application doesn’t have an unhandled error. This is accomplished with little or no performance penalty and with low impact on existing code.
Basic exceptions are not terribly difficult to learn, and you should begin using them in your programs as soon as you can. Exceptions are one of those features that provide immediate and significant benefits to your project.
