哪位高手能帮帮我啊，这个问题我想了好久，可总是达不到我的心意。
我想要用类写一个程序，目的是能输入学生的姓名，成绩，和出生年月日。然后能显示每人学生的属性。可是当我输入姓名为tom 时就 出现错误输出。
所以姓名只能用一个字母表示，否则出错。除此之外，当输入两个学生时，其它属性输出也不正确，都以第二次输入的输出。太气人了。
程序如下，如果哪位朋友有时间的话，请看一下，帮我改一下，谢谢了！！！
#include<iostream.h>

class Cstudent
{
public:
int p;//p 的作用将在类外定义的函数中的i传回类，再传给另一个构造函数。总觉的这里不爽，可又不知怎么改好。
student()
{struct student
{char name[60];
float grade;
int biryear;
int birmonth;
int birday;
};
};
get_student();
cout_student();
private:
char name[60];
float grade;
int biryear;
int birmonth;
int birday;
};
Cstudent::get_student()
{
int i,j;
cout<<"请输入要输入学生的数目"<<endl;
cin>>i;
p=i;
cout<<"请依次输入学生的姓名，成绩和出生年月日"<<endl;
for(j=0;j<i;j++)
{
cin>>name[j]>>grade>>biryear>>birmonth>>birday;
}
}
Cstudent::cout_student()
{int i=p,j;
cout<<"学生的姓名，成绩和出生年月日如下"<<endl;
for(j=0;j<i;j++)
{cout<<name<<"的成绩为"<<grade<<"出生年月日为"<<biryear<<"年"<<birmonth<<"月"<<birday<<"日"<<endl;
}
}
void main()
{
Cstudent one;
one.student();
one.get_student();
one.cout_student();
}

个人认为，你的程序有多出不合理之处，这是我的一
种改法，初学C++能力有限，希望能给你点启发

#include<iostream.h>

}

void main()
{ int i;
const MAX=100;
cout<<"请输入要输入学生的数目"<<endl;
cin>>i;

Cstudent student[MAX];//student 的每一个元素都是一个对象
for(int j=0;j<i;j++) student[j].get_student(j);
for(j=0;j<i;j++) student[j].cout_student(j);
}

#include<iostream.h>

class Cstudent
{
public:

int studentCnt;
};

Cstudent::Cstudent()
{
for (int i=0; i<60; ++i)
name[i] = 0;
grade = 0;
biryear = 0;
birmonth = 0;
birday = 0;
}

Cstudent::get_studentCnt()
{
return studentCnt;
}

Cstudent::set_studentCnt(int icnt)
{
studentCnt = icnt;
}

Cstudent::get_student()
{
int stdCnt;

cout<<"请输入要输入学生的数目"<<endl;
cin>>stdCnt;
set_studentCnt(stdCnt);
cout<<"请依次输入学生的姓名，成绩和出生年月日"<<endl;
for(int i=0;i<stdCnt;i++)
{
cin>>stdArr[i].name
>>stdArr[i].grade

}
}
Cstudent::cout_student()
{
cout<<"学生的姓名，成绩和出生年月日如下"<<endl;
for(int i=0;i<get_studentCnt();i++) {

<<stdArr[i].birday<<"日"<<endl;
}
}
void main()
{
Cstudent *one = new Cstudent();

one->get_student();
one->cout_student();
}

如果你想每输入一个学生的信息就出现一次“请依次输入学生的姓名，成绩和出生年月日”的提示那么get_student()
函数的（cout<<"请依次输入学生的姓名，成绩和出生年月日"<<endl;）这句代码放到循环内便可

1. 类声明头文件

用构造函数初始化对象需要多个参数
不太方便
