Exception handling before and after main

Question

Is it possible to handle exceptions in these scenarios:

1. thrown from constructor before entering main()
2. thrown from destructor after leaving main()

Answer 1

Short answer: no.

Any global object that throws an exception in its constructor will cause an unhandled exception (that is, terminate be called).

Any class that throws an exception in its destructor is a broken class.

Using the singleton pattern rather than globals will give you more options.
