using namespace std;

class Student {

    Student(string name, int regNumber, int marks=0);
    string GetName() const {
        return name;
    }
    int GetRegistrationNumber() const {
        return registrationNumber;
    }
    int GetTotalMarks() const {
        return totalMarks;
    }
    void SetTotalMarks(int marks) {
        totalMarks = marks;
    }
    void PassExam() const;

private:
    string name;
    int registrationNumber;
    int totalMarks;
};

Student::Student(string name, int regNumber, int marks) :
    name(name), registrationNumber(regNumber), totalMarks(marks)
{}

void Student::PassExam() const
{
    cout << "The student " << name;
    if (totalMarks < 50) {
        cout << " has not pass the Exam";
    }
    else {

int main()

    Student st2("Bob Brown", 45678, 80);

    st1.PassExam();
    st2.PassExam();
