Why are exceptions used in programming?

Exceptions provide programmers with an alternative method to solve a problem presented under normal conditions in the normal program flow as presented in a try block.

Exceptions allow you to "bail out" of a piece of code that reaches a situation where it cannot complete execution.

Exceptions allow a program to crash when the preconditions it requires to operate are not met.

Exceptions are used when the input provided is valid and can be used in multiple blocks of code.
