Is Reference type in C++ a POD type?

Question

Is Reference type in C++ a POD type too? Is int& is a POD type? and what about

struct Q { int& i; }

Anyone can help me?

Answer 1

There is a standard way (using C++11) to determine that at compile time.

#include 
#include 

struct Q
{
    int& i;
};

int main()
{
    std::cout << std::is_pod::value << "\t";
    std::cout << std::is_pod::value << "\t";
    std::cout << std::is_pod::value << "\n";
}

The output will be 1 0 0, so no a reference to int is not POD.
