why?
智能指针帮助c++使用者更好的管理内存
how?
使用方法
eg:
std::shared_ptr<int> foo = std::make_shared<int> (10);
// same as:
//std::shared_ptr<int> foo (new int(10));
std::cout << "*foo: " << *foo << std::endl;
eg:
class A {
public:
A(int i) : m_i(i) { }
void foo() {
std::cout << m_i << std::endl;
}
private:
int m_i;
};
typedef std::shared_ptr<A> A_PTR;
A_PTR aPtr = std::make_shared<A>(10);
std::cout << aPtr->foo() << std::endl;
