弱问：初学vc静态成员，出错：'Student' followed by 'int' is illegal (did you forget a ';'?)

[zkl0304]

#include<iostream.h>
class Student
{
public:
Student(int StudentNo=0)
{
cout<<"creat one student\n" ;
NoOfStudents++;
cout<<"NoOfStudents"<<NoOfStudents;
StudentNo = 9022100 + NoOfStudents;
cout<<"StudentNo"<<StudentNo<<endl;
}
~Student()
{
cout<<"destruct one student \n";
NoOfStudents--;
}
static int number()
{
return NoOfStudents;
}
protected:
static int NoOfStudents;
int StudentNo;
}
int Student::NoOfStudents=0;
void fn()
{
Student s1;
Student s2;
cout<<Student::number()<<endl;
}
void main()
{
fn();
cout<<Student::number()<<endl;
}



出错：

还有，静态成员初始化应该放到哪里最好？

[一个傻冒]

你类定义完之后少了一个分号.加上就好了.

#include<iostream.h>
class Student
{
public:
Student(int StudentNo=0)
{
cout<<"creat one student\n" ;
NoOfStudents++;
cout<<"NoOfStudents"<<NoOfStudents;
StudentNo = 9022100 + NoOfStudents;
cout<<"StudentNo"<<StudentNo<<endl;
}
~Student()
{
cout<<"destruct one student \n";
NoOfStudents--;
}
static int number()
{
return NoOfStudents;
}
protected:
static int NoOfStudents;
int StudentNo;
}; //你这里少了一个分号.呵呵.
int Student::NoOfStudents=0;
void fn()
{
Student s1;
Student s2;
cout<<Student::number()<<endl;
}
void main()
{
fn();
cout<<Student::number()<<endl;
}

大哥（姐），谢谢哦！

惭愧，学习中...
