Question

From C++ FAQ

“How can you reseat a reference to make it refer to a different object?”

But when I do this it compiles and executes fine.

    int f = 5;
int y =4;
int& u = f;
u = y;
B& bRef = B();
bRef = B();

This code is inside my main() function.

Answer 1

You don’t reseat the reference, you simply assign to the referred object.

#include <iostream>

struct X{
  void operator=(X const&){
    std::cout << "Woops, assignment!\n";
  }
};

int main(){
 X x, y;
 X& rx = x;
 rx = y;
}

Guess what this prints.
