A) unable to resume
B) exited back in search of a handler
C) placed elsewhere on the stack
D) moved off the stack and onto the heap

Question

Quizplus · Accepted Answer

When an exception is thrown, control is exited back in search of a handler that can catch the exception. This process is known as stack unwinding. The search for a handler begins from the point where the exception is thrown and continues through the call stack until a suitable handler is found or until the main function is reached, at which point the program terminates. Option A is incorrect because control can be resumed if a suitable catch handler is found. Option C is incorrect because the placement of control does not change during stack unwinding. Option D is also incorrect because stack unwinding does not involve moving data onto the heap.
