What does the placement new syntax allow in C++?

Allocation of memory at a specific address
Calling the destructor explicitly
Conversion of dynamic memory to static memory
Skipping constructor call for an object

The correct answer is: Allocation of memory at a specific address

The placement new syntax allows for the allocation of memory at a specific address in C++. This can be useful for implementing custom memory management techniques or for optimizing performance in certain situations. All of the other options are incorrect because they either refer to different features of C++ or are not related to memory allocation. Option B, calling the destructor explicitly, is a feature of C++ but is not specific to the placement new syntax. Option C, conversion of dynamic memory to static memory, is not related to memory allocation but rather to the type and lifetime of the memory being used. Option D, skipping constructor call for an object, is not a valid operation and would result in undefined behavior. Therefore, the correct answer is A.
