C++中构造函数、参数列表、析构函数、拷贝构造函数、动态分配的数组变量的删除的简单例子

#include<iostream>
#include<string>
using namespace std;
class Person
{
private:
char *name,*another;
int age;
public:
Person(char *Name,int Age);
void setAge(int x);
void print();
~Person();
Person(const Person &p);
};
Person::Person(char *Name,int Age):age(Age)
{
name=new char[strlen(Name)+1];
another=char[10];
strcpy(name,Name);
//age=Age;
cout<<"constructor……"<<age<<endl;
}
void Person::setAge(int x){age=x;}
void Person::print()
{
cout<<name<<":"<<age<<endl;
}
Person::~Person()
{
delete name;
delete [another];
cout<<"destructor……"<<age<<endl;
}
Person::Person(const Person &p):age(p.age)
{
name=new char[strlen(p.name)+1];
strcpy(name,p.name);
//age=p.age;
cout<<"copy constructor……"<<age<<endl;
}
int main()
{
Person object1("zhangsan",19);
Person object2=object1;
object1.setAge(1);
object2.setAge(2);
object1.print();
object2.print();
}
