如何使某个数为一个类？

[海岛椰风]

比如先建一个student类
然后输入整数，如果此整数大于0，则这个数属于student类中的数 这怎么实现？

lz，没看明白...

就是对输入的数判断，如果输入的数大于0，这将此数放入student类

[CppPower]

[code=C/C++]]#include <iostream>
using namespace std;

class student
{
private:
int m_iID;
public:
void SetID(int id){m_iID=id>0?id:0;}
int GetID(){return m_iID;}
};

int main()
{
student s;

int id=0;
cin>>id;
s.SetID(id);
cout<<s.GetID()<<endl;

system("pause");
return 0;
}

[/code

这个类有什么用？

恩，谢了

#include <vector>
#include <iostream>

int main(void)
{
int i;
std::vector <int> student;
std::vector <int>::iterator student_Iter;

std::cin>>i;

while(i)
{
if(i > 0) student.push_back(i);
std::cin>>i;
}

std::cout << "student =" ;
for ( student_Iter = student.begin( ) ; student_Iter != student.end( ) ; student_Iter++ )
std::cout << " " << *student_Iter;
std::cout << std::endl;

}
