What will be the output of the following C++ code?
#include <iostream>
#include <string>
#include <cstdlib>
using namespace std;
int main(int argc, char const *argv[])
{
int a = 5;
int *p = &a;
int *(&q) = p;
cout<< q;
return 0;
}
a) 5
b) Address of pointer a
c) Address of pointer p
d) Error

Answer: b
Explanation: The program is correct so the the program runs perfectly. It is way to assign pointers to references. The program prints the address of a because it is an alias for pointer p and pointer p stores the address of a therefore answer is address of a.
