#include<iostream>
#include<string>
using std::string;
using std::cout;
using std::endl;
class Student
{

private:
int m_num;
string m_name;
char m_sex;
public:
Student(int num,string name,char sex):m_num(num),m_name(name),m_sex(sex)
{
cout << "Constructor  called." << endl;
     }
~student()
{
cout << "Destructor  called." << endl;
     }
 void display ()
     {
         cout << "num:" << num << endl;
         cout << "name:" << name << endl;
         cout << "sex:" << sex << endl << endl;
}
};
int main()
 {
     Student stud1 (101, "Wangli", 'f');
     stud1.display ();
     Student stud2 (102, "Limin", 'm');
     stud2.display ();
     return  0;
 }

 

细节问题。看看编程软件下面的提示。双击可以看看那里出问题。函数后面不用分号void  display()
{cout<<"num:"<<num<<endl;
cout<<"name:"<<name<<endl;
cout<<"sex:"<<sex<<endl<<endl;}
private:
    int  num;
    string  name:
    char   sex;
}
还有int main()
{} 括号括回去
