Compare and contrast dynamic memory allocation and deallocation operators new, new [], delete and delete [].

What will be an ideal response?

Operator new creates an object and dynamically allocates space in memory for that object. Operator delete destroys a dynamically allocated object and frees the space that was occupied by the object. Operators new [] and delete [] are used to allocate and deallocate arrays dynamically. Operator delete [] ensures that the destrctor is called for each element in the array before the array is reclaimed.
