Question:
Which of the following statement is correct about the program given below?

#include<iostream.h> 
struct Bix
{
    short n;
};
int main()
{
    Bix b;
    Bix& rb = b;
    b.n = 5;
    cout << b.n << " " << rb.n << " ";
    rb.n = 8;
    cout << b.n << " " << rb.n;
    return 0; 
}

1.It will result in a compile time error.

2.The program will print the output 5 5 5 8.

3.The program will print the output 5 5 8 8.

4.The program will print the output 5 5 5 5.
