从文本文件读取直到 EOF 无限循环

如何解决从文本文件读取直到 EOF 无限循环

我在我的学校编程项目中工作,我想出了“学生经理计划”的想法。

name,roll,year,group,course,adress,email,contact,grade 作为变量存储在名为 Student 的类中。

学生的数据由用户键盘输入写入并按对象保存在studentRecord.txt文件中。 我怎样才能防止这个 while 循环成为一个非无限循环。我找不到这个问题的解决方案。

//displaying Students Record Table
void Student::display() {
    system("cls");
    ifstream file;
    int total = 1;
    int x;
    cout << "\n-----------------------------Students Record Table-----------------------------" << endl;
    file.open("studentRecord.txt");
    if (!file) {
        cout << "\n\t\t\tNo Data Is Present.";
        file.close();
    }
    else {
        file >> name >> roll >> year >> group >> course >> adress >> email >> contact >> grade;
        while(!file.eof()) {
            cout << "\n\n\t\t\t Student Consecutive Number: " << totaL++ << endl;
            cout << "\t\t\t Student's Name: " << name << endl;
            cout << "\t\t\t Student's ID Number:  " << roll << endl;
            cout << "\t\t\t Student's Year:  " << year << endl;
            cout << "\t\t\t Student's Group:  " << group << endl;
            cout << "\t\t\t Student's Course: " << course << endl;
            cout << "\t\t\t Student's Adress: " << adress << endl;
            cout << "\t\t\t Student's Email: " << email << endl;
            cout << "\t\t\t Student's Contact: " << contact << endl;
            cout << "\t\t\t Student's Final Grade: " << grade << endl;
            file >> name >> roll >> year >> group >> course >> adress >> email >> contact >> grade;
        }
        if (total == 0) {
            cout << "\n\t\t\tNo Data Is Present.";
        }
    }
    do {
        cout << "\n\t\t\t If You Want to Back at prevIoUs page press 0 and Enter: ";
        cin >> x;
        if (x == 0) {
            file.close();
        }
    } while (x != 0);
}
