std::shared_ptr 和普通指针的转换

相互转化见示例

struct test
{
     int num;
     string name;
};

test* pTest = new test();
std::shared_ptr<test> ptr_test = std::shared_ptr<test>(pTest); //普通指针转shared_ptr

std::shared_ptr<test> ptr_test2 = std::make_shared<test>();
test* pTest2 = ptr_test2.get(); //shared_ptr转普通指针
