Error at constructor : Expected an identifier?

I am working with a bunch of classes with composition and I keep getting this error (Expected an identifier) when I try to implement the constructor , here the class header:

#ifndef STUDENT_H_
#define STUDENT_H_

#include "University.h"
class Student {
public:
    Student(); // constructor
    friend ostream & operator<<(ostream &, Student &); // print the student data
    friend istream & operator>>(istream &, Student &); // to read student data
private:
    const int id; 
    string name; 
    int marks[5];
    Date admissionDate; // Composition
    University university;  // Composition
};

#endif

what do I need to do to solve this error ?

here's the cpp but I still did not implement the other io functions because I want to solve that error first..

#include "Student.h"
Student::Student(){}
ostream & operator<<(ostream &, Student &){} 
istream & operator>>(istream &, Student &){}

Since a Student has a const int id member, you need to initialize it in the constructor's initialization list. E.g.:

Student::Student() : id(0)
{ }

Your constructor should be defined the following way

Student::Student() { /* some code */ }
