What happens when new cannot allocate the requested memory in its normal form?

Options

  • A. It normally returns NULL
  • B. It normally throws std::bad_alloc
  • C. It always terminates the operating system
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. It normally throws std::bad_alloc

Detailed Explanation

Answer: It normally throws std::bad_alloc

In its normal form, the C++ new operator throws a std::bad_alloc exception if the requested memory cannot be allocated.

This allows the program to handle allocation failure using exception handling.

For example, a program can use try and catch to handle the allocation failure.
