C++学习第11课，类的继承初体验（面向对象编程）

#include <stdio.h>

#include <iostream>
using namespace std;
class Person{
private:
char *name;
int age;
public:
Person()
{
this->name = NULL;
this->age = 0;
}
Person(char* name, int age = 0):age(age)
{
this->name = new char[strlen(name)+1];
strcpy(this->name, name);
}
~Person()
{
if(this->name)
{
delete this->name;
}
cout<<"~Person()"<<endl;
}
void setname(char* name)
{
if(this->name)
{
delete this->name;
}
this->name = new char[strlen(name)+1];
strcpy(this->name, name);
}
void setage(int age)
{
this->age = age;
}
char* getName(void)
{
return this->name;
}
int getAge(void)
{
return this->age;
}
void printInfo(void)
{
cout<<"(name = "<<this->name<<" ,age = "<<this->age<<")"<<endl;
}
};
class Student : public Person {
};
int main(int argc, char **argv)
{
Student x;
x.setname("xiaoming");
x.setage(23);
x.printInfo();
return 1;
}
解释：class Student : public Person 类Student继承Person，也可以说类Student是Person的子类或派生类，Person是Student的父类。
