What is exception handling class 12?
Raise and assert statements are used to raise exceptions. • The process of exception handling involves writing additional code to give proper messages or instructions to the user.
This prevents the program from crashing abruptly.
The additional code is known as an exception handler..
What is exception handling in computer science?
Exception handling is the process of responding to unwanted or unexpected events when a computer program runs.
Exception handling deals with these events to avoid the program or system crashing, and without this process, exceptions would disrupt the normal operation of a program..
What is the class of exception handling?
The Exception class has a set of sub-classes for handling different types of exceptions such as IOException, NotBoundException, and NotOwnerException etc.
All the subclasses of the Exception class are in the form of Throwable that indicates the conditions that an application wants to catch..
What is the need for exception handling in Python Class 12?
An exception is a Python object that represents an error.
When an error occurs during the execution of a program, an exception is said to have been raised.
Such an exception needs to be handled by the programmer so that the program does not terminate abnormally..
Why do we need error handling?
When we neglect to make our code resilient to errors, it makes debugging it more difficult than it should be.
That's what error handling essentially does … it doesn't ELIMINATE errors in our code.
But it helps make your code smarter about how to deal with things that unexpectedly go wrong..
Why do we need exception handling in programming?
Exception handling is the process of responding to unwanted or unexpected events when a computer program runs.
Exception handling deals with these events to avoid the program or system crashing, and without this process, exceptions would disrupt the normal operation of a program..
Why exception handling is needed in C++?
Exception handling is a mechanism that separates code that detects and handles exceptional circumstances from the rest of your program.
Note that an exceptional circumstance is not necessarily an error.
When a function detects an exceptional situation, you represent this with an object..
- An exception is an exceptional or unexpected event that occurs when a program is running.
- Explanation: We need to handle exceptions in a program to avoid any unexpected behaviour during run-time because that behaviour may affect other parts of the program.
Also, an exception is detected during run-time, therefore, a program may compile successfully even with some exceptions cases in your program. - Handling Exceptions in C.
The basic function of exception handling is to transfer control to an exception-handler when an error occurs, where the handler resides somewhere higher up in the current function call hierarchy.
Standard C has a mechanism to accomplish this: setjmp() and longjmp(). - The statements inside the finally block are always executed regardless of whether an exception has occurred in the try block or not.
It is a common practice to use finally clause while working with files to ensure that the file object is closed.
