[Solved] Pointer variable of a linked list: difference between the variable, reference to the variable, and pointer to the variable [closed]

Question

No! You’re talking some mix-up of C and C++. This is C code. C does not have references.

The & operator can be applied to objects in order to retrieve their address in memory, yielding a pointer, in both C and C++. It ain’t got nothing to do with references. Even in C++.

In C++, you can use the ampersand character (&) to define a reference:

int i;
int& b = i;    // reference referencing i

This is not possible in C, though.

BTW, printf uses specific format specifiers for specific types. %d is for ints. For pointers (like &i), use %p. Wrong usage of the wrong format specifier is undefined behavior.
