All exceptions end up in std::terminate() in the end.
If your application MUST NOT crash (e.g. you are coding a safety critical system) then you would be wise to override std::terminate() by passing a pointer to your own exception handler to std::set_terminate().

Your handler should then take whatever action is appropriate to keep your system safe.

In what language? Can you give an example of an exception that's not caught by try-catch?

catch throwable in java

Make your own exception.

Make a custom exception handler..

public class InvalidOptionCountException extends Exception {
	
	public InvalidOptionCountException(int count) {
		System.out.println("Invalid count: " + count);		
	}
	
}

Yes, we can handle those exceptions which are not handled in try catch block.
We can handle the exception in app file.
All the errors which get escaped from catch block, handles in app file, here we can manage it according to our need. Thus preventing to be get crashed.
