What other purpose exception has

Question

Hi

I am aware that exception is to avoid crash and control some random issues into code..

Does it has other purpose as well ? What is best suited and why for exception from below option :

1. To come out of function
2. To return value from function
3. To come out of constructor
4. To come out of destructor

Answer 1

That's the main purpose of exceptions, to avoid code crashes. It is best suited for 1 and 2. This is because functions must accomplish a task whether or not exceptions occur. Exception handlers will be of great use here because they can help the function return a default value if an exception occurs

For 3 & 4 it should be just performing another operation (like assigning a default value) should an exception occur rather than breaking out of the class' constructor/destructor

Answer 2

Okay...sounds good.... thanks Emeh Matthew
