Introduction
Exception handling is a common error handling mechanism in programming that allows programs to gracefully handle errors or unusual conditions when they are encountered. In C++, the exception class is an important exception handling tool.
When an error or exception occurs in the program, we can use the exception class and its subclasses to throw an exception. These exceptions can be caught and handled by other code to avoid program crashes or unexpected behavior.
Following are the basic steps to use exception classes:
- Define exception class: Define your own exception class in the program, or find a suitable exception class in the C++ standard library, such as std::exception and its subclasses.
- Throwing an exception: When the program encounters an error or an abnormal situation, the exception object is thrown using the throw statement.
- Catching exceptions: Use try blocks to catch code blocks that may throw exceptions, and handle exceptions in catch blocks.
The following is the method of using the exception class and exception handling in the secondary development of NX.
