(Local Variable Destructors) Write a program illustrating that all destructors for objectsconstructed in a block are called before an exception is thrown from that block.

[Access Control Policy]: A computer system usually implements the exception handling mechanism. Like the interrupt handling mechanism, the original program flow will be stopped until the exception is handled. For example, when a program is calculating c=a/b, and for some reason b was set to 0, the program will encounter the "Division by Zero" exception. The control will be given to the exception handler, and the recovery action could be "report only", "return to the next instruction", "purge the program", etc., based on the severity of the problem. From the abov information, we can conclude: A computer system can integrate both Discretionary Access Control (DAC) and Mandatory Access Control (MAC) security policies An administrator can inhibit the exception handling The exception handling mechanism is like the Mandatory Access Control security policy, no matter which user caused the exception (even the administrator), the program should be stopped, and the control should be given to the…

(Throwing Exceptions from a catch) Suppose a program throws an exception and the appropriate exception handler begins executing. Now suppose that the exception handler itself throwsthe same exception. Does this create infinite recursion? Write a program to check your observation.
