std::shared_ptr初始化的几种方式

1.1 构造函数初始化

std::shared_ptr pointer(new int(1));

std::shared_ptr pointer1 = pointer;

std::shared_ptrstd::string ss(new std::string("AAA"));

std::shared_ptrstd::string = std::shared_ptrstd::string(new std::string("AAA"));

1.2 std::make_shared初始化

std::shared_ptr p3 = std::make_shared();

std::shared_ptr p2 = std::make_shared("hello");

//auto关键字代替std::shared_ptr，p5指向一个动态分配的空vector
auto p5 = make_shared<vector>();

1.2 reset初始化

std::shared_ptr pointer = nullptr;
pointer.reset(new int(1));
