由于Ubuntu手机平台安全的限制，在Ubuntu手机的应用中我们只能访问自己的空间．如果我们所需要访问的文件不存在于我们应用所在的空间，我们是没有办法访问到的．我们的应用只能访问系统提供的库．如果系统没有所需要的库的话，我们通过可以通过如下的方法实现：$ git clone https://github.com/liu-xiao-guo/studentlib_shared
#include<string>
class Student{
private:
std::string name;
public:
Student(std::string);
virtual void display();
};
#include <iostream>
#include "Student.h"
using namespace std;
Student::Student(string name):name(name){}
void Student::display(){
cout << "A student with name " << this->name << endl;
}
