How can we restrict dynamic allocation of objects of a class using new?
(A) By overloading new operator
(B) By making an empty private new operator.
(C) By making an empty private new and new[] operators
(D) By overloading new operator and new[] operators

Answer: (C)

Explanation: If we declare new and [] new operators, then the objects cannot be created anywhere (within the class and outside the class)
See the following example. We can not allocate an object of type Test using new.

#include <stdlib.h>
#include <stdio.h>
#include <iostream>

using namespace std;

class Test {
    void* operator new(size_t size) {}
    void* operator new[](size_t size) {}

int main()
    Test *obj = new Test;
    Test *arr = new Test[10];
    return 0;
