第5周项目--程序阅读——指针、const、static

#include <iostream>
using namespace std;
class base
{
private:
    int m;
public:
    base() {};
    base(int m){this->m=m;}
    int get(){return m;}
    void set(int m){this->m=m;}     <span style="color:#ff0000;">//要用this指针区别
</span>};//base_end

int main()
{
    base *ptr;        <span style="color:#ff0000;">//定义指向类类型的指针
</span>    ptr=new base[2];   <span style="color:#ff0000;">//开辟动态存储，数组
</span>    ptr->set(30);
    ptr=ptr+1;
    ptr->set(50);
    base a[2]= {1,9};
    cout<<a[0].get()<<","<<a[1].get()<<endl;
    cout<<ptr->get()<<",";
    ptr=ptr-1;
    cout<<ptr->get()<<endl;
    delete[] ptr;
    return 0;
