从文本文件读取直到 EOF 无限循环

问：

我正在为我的学校编程项目工作，我想出了“学生经理计划”的想法。

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

学生的数据由用户键盘输入写入，并按对象保存在文件中。 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。studentRecord.txt

//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;
