C++ | References | Question 6
  • Difficulty Level : Medium
  • Last Updated : 01 Mar, 2013

Which of the following is FALSE about references in C++
(A) References cannot be NULL
(B) A reference must be initialized when declared
(C) Once a reference is created, it cannot be later made to reference another object; it cannot be reset.
(D) References cannot refer to constant value


Answer: (D)

Explanation: We can create a constant reference that refers to a constant. For example, the following program compiles and runs fine.

#include<iostream>
using namespace std;

int main()
{
  const int x = 10;
  const int& ref = x;

  cout << ref;
  return 0;
}
