What is exception handling ? What is the sequence of events when an exception occurs ? Write a C++ program that uses exception handling to handle the errors caused, when a number is divided by zero.
Exception handling is a mechanism in programming languages, including C++, that allows the identification and management of runtime errors in a more controlled manner. In C++, exception handling is done using three keywords: `try`, `catch`, and `throw`.
1. Try Block:
- The code that might throw an exception is enclosed within a `try` block. It is the section of code where you anticipate potential errors.
2. Throw Statement:
- If an error occurs in the `try` block, you can use the `throw` statement to raise an exception. This is typically done with an object that represents the error.
3. Catch Blocks:
- The `catch` block is used to catch and handle the exceptions thrown in the `try` block. Each `catch` block is associated with a specific type of exception. If an exception of that type is thrown, the corresponding `catch` block is executed.
4. Exception Handling Hierarchy:
- C++ supports a hierarchy of exception classes. You
