If a destructor throws an exception, the instance is left in an invalid state. When an exception is thrown, the destructor automatically terminates at the point of the throw, unwinding the call stack until an exception handler is found (if one is provided). However, any resources yet to be released by the destructor, including all the instance's base classes, cannot be destroyed.
When writing your own destructors, it is important to never throw an exception. If an exception could be thrown from within your destructor, you must catch it and handle it within the same destructor -- you must not rethrow the exception.

Is constructors throws exception in C plus plus?
We must throw an exception from constructor in C++, but remember that in case of exception in Ctor, destructor will not be executed and you may have memory leaks. SO make sure all the data members must clean up their mess own. e.g. use smart pointers so in case of excpetion memory will released to free storage.

IS Throwing an exception always causes program termination?
No Not necessarily.. You can catch an exception and then continue to execute your program as if nothing happened. If in your catch block you have code like System.exit then your program would terminate.
Can you overload destructor for your class?
No. Classes can only have one destructor, whether you define one yourself or allow the compiler to generate one for you. The compiler-generated destructor is public by default, does not release any memory allocated to any class' member pointers, and is non-virtual, which are the three main reasons for defining your own.
What is the difference between destructors in c plus plus and c sharp?
In C# only class instances can have a destructor, whereas both class and struct instances can have a destructor in C++. While syntactically similar, a C++ destructor executes exactly as written, whereas a C# destructor merely provides the body of the try clause of the class' finalize method.
You cannot throw an exception from a destructor?
Sure you can, but it's never a good idea. You must never allow an exception to escape from a destructor. To do so would terminate the destructor prematurely, unwinding the call stack in search of an exception handler. This means that any remaining resources consumed by the instance, including its base classes, would be left in an invalid state with no possible way to recover those resources besides terminating the program. Any object that has the potential to throw an exception during its own destruction should always be treated with suspicion; it is a major design flaw.
