error: no matching function for call to'arch::newsucc(). I tried everything,but nothing worked [duplicate]

I tried to call the function print and it worked.The function newsucc the only one who had this problem. I tried to rename it, and made the function at class national like this virtual void newsucc(int students, int succ) { }; and a lot of things but nothing worked the code about an exam at our country that could national exam, we should use class and inheritance in c++ the base class is national the child class are arch and IT

#include <iostream>
#include <string>
using namespace std;

class National {
protected:
    string name;
    int students;
    int succ;

public:
    National()
    {
        name = "";
        students = 0;
        succ = 0;
    }
    National(string ex, int s, int su)
    {

        name = ex;
        students = s;
        succ = su;
    }
    National(National&N ) {

        this->name = N.name;
        this->students = N.students;
        this->succ = N.succ;

    }
    void print()
    {
        cout << "The results of the National Exam" << endl;

    }

    virtual void newsucc() { };
