发一下报错截图吧，不然不好说→_→

第一个
第三个直接死循环了

#include <iostream>
#include <memory>
using namespace std;
int main(){
int i=10;
auto_ptr<int> ap1(new int(4)),ap2;
ap2=ap1;
cout<<*ap2;
cout<<*ap1<<endl;
char *c;
shared_ptr<char> sc;
sc=c;
sc=new char(10);
}
这个要怎么改

第一个main函数里面不能嵌套函数，第三个智能指针没有开辟空间，第四个这样写：
int i = 10;
auto_ptr<int> ap1(new int(4)), ap2;
ap2 = ap1;
cout << *ap2;
cout << *ap1 << endl;
char *c;
c = new char(10);
shared_ptr<char> sc(c);

怕不是一个学校的
