Why Can't Make a Reference To Pointer for Constant Assign a String Literal

I can make pointer point to string literal, it will cast string literal to constant pointer, but reference to pointer can't assign string literal, for example:

 const char *&text = "Hello, World\n"; 

There's an error, the compiler says I can't cast an array to pointer reference, I am curious about it, why it isn't it correct?

The conversion to a const char* can be seen as temporary returned by value. You can't bind a reference to a non-const temporary. To extend the life of a temporary you would have to make the pointer const too. If that's not an option, you'll have to bind the reference to a pointer that is not temporary.

Example:

#include <iostream>

int main() {
    const char* foo = "foo\n";
    const char* bar = "bar\n";
    const char*& text = foo;
    
    std::cout << text;
    foo = bar;
    std::cout << text;
}

foo
bar
