我被要求编写一个程序，其中有3个班级为学生，第二个为日期，最后一个对象是地址 我必须在班级学生的主要课程中创建一个对象，该班级学生除了课程日期的3个日期和班级地址的地址之外还有班级学生的所有属性 所以我写了代码，我在类日期中使用了一个函数，以确保日期是正确的m / d / y形式，我也使用了set和get函数 但问题是当我编译代码时，最终结果显示所有值为＆＃34; 1＆＃34;
这是我的代码：// class date header：
#ifndef Date_H
#define Date_H
class Date
{
public:
Date( int , int , int ); // default constructor
void setmonth(int &);
void setday(int &);
void setyear(int &);
int getmonth() const;
int getday() const;
int getyear() const;
void print() const; // print date in month/day/year format
~Date(); // provided to confirm destruction order
private:
int month; // 1-12
int day; // 1-31 based on month
int year; // any year
// utility function to test proper day for month and year
int checkDay( int );
};
#endif
//班级日期来源：

// call utility function checkDay to confirm proper
// value for day.

{
if (mn > 0 && mn <= 12 ) // validate the month
month = mn ;
else {
month = 1;
cout << "Month " << mn << " invalid. Set to month 1.\n";
}
month = mn ; // validate the month
year = yr; // should validate yr
day = checkDay( dy ); // validate the day
cout << "Date object constructor for date ";
print();
cout << endl;
}

答案 0 :(得分：0)
问题是你在构造函数的末尾打印：
使用&将获取数据的地址（这里甚至是你的memeber函数），而不是数据本身。
纠正于：
cout << "Student object constructor : "
<< Student::getFirst_Name() << ' ' << Student::getLast_Name() << ' ' << Student::getPhone_Number() << ' ' << Student::getMobile_Number() << ' ' << Student::getSpecialization() << endl ;
}
