Fix C++ Invalid Throw Errors: Quick Guide

In C++, the throw keyword is used to throw exceptions. If your throw is invalid, it may be due to the following reasons:

1. Incorrect exception type: Make sure that the type of exception you are throwing matches the one specified in your catch statement. If they do not match, the exception will not be caught.
2. If you don’t catch exceptions: If you don’t include a try-catch statement to catch exceptions where they’re thrown, the exceptions won’t be handled. You can add a try-catch statement where the function is called to catch exceptions and handle them in the catch block.
3. Exceptions being swallowed: Sometimes, exceptions are swallowed by other code, causing them to not be handled properly. Make sure that there are no other places in your code where exceptions are being caught and left unhandled.
4. Exception interrupted: If the program is aborted or unexpectedly interrupted while throwing an exception, the exception may not be properly thrown. Make sure there are no other potential causes of interruption in your code.
