What is what does exception mean?

An exception in computer programming is an event that interrupts the normal flow of program execution. It is an error or anomaly that occurs during the execution of a program due to unforeseen or unexpected conditions. Exceptions can occur for various reasons, such as when a program tries to access an invalid memory location, divide by zero or encounter an unexpected input. When an exception occurs, the program stops running, and an error message is displayed. Exception handling is a mechanism in programming that allows programmers to catch, handle, and recover from these errors. By using exception handling, programmers can write code that gracefully deals with errors and avoids crashing the program.
