vector的类型是智能指针，该怎么循环往容器中放值?

Question

```vector<shared_ptr<int>> v; 怎么循环往里放值呢，有代码可以参考下吗？往模板里放智能指针类型

Answer 1

v.push_back(ptr)
不管是什么类型的变量，添加元素都是push_back

int b = c = 25;
shared_ptr<int> pa = make_shared<int>(25);
shared_ptr<int> pb = make_shared<int>(b);
shared_ptr<int> pc = shared_ptr<int>(pb);

v.push_back(pa);
v.push_back(pb);
v.push_back(pc);
v.push_back(make_shared<int>(25));
