Exception handling in C++ is a mechanism that allows a program to handle errors or exceptional situations during runtime by using try, catch, and throw statements.
Exception handling is a crucial concept in programming that allows developers to deal with unexpected or exceptional situations that may occur during the execution of a program. These exceptional situations are often referred to as “exceptions.” Here are some reasons why exception handling is importa...
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()andlongjmp(). Example 1 shows a simple impleme...
Exception Handling in C++ It is not necessary that this method works for every program you write to automatically and silently recover from all exceptional circumstances, it is clear that you must do better than crashing. Exception provides a method to control exceptional conditions (like run time...

This would produce the following result − MyException caught C++Exception Here,what()is a public method provided by exception class and it has been overridden by all the child exception classes. This returns the cause of an exception.
The process of handling these types of errors in C++ is known as exception handling. In C++, we handle exceptions with the help of thetryandcatchblocks, along with thethrowkeyword. try-code that may raise an exception throw- throws an exception when an error is detected ...
