Cannot understand this piece of code (operator &) in C++

Question

I don't understand why the & operator which mainly means "adress of" is there, I used this operator in C but in this code I don't understand it's purpose.

#ifndef _STUDENT_
#define _STUDENT_

struct Student {
    char* name;
    int mark;
};

void InitStudent(Student&);
void ShowStudent(Student);
void DeleteStudent(Student&);

#endif

Answer 1

The & in Student& means that you are passing a (non-const) reference to a Student instance. It's not the C "address-of" operator.
