推导指引(C++17)

 

template< class T, class U, class V > std::basic_ostream<U, V>& operator<<( std::basic_ostream<U, V>& os, const std::shared_ptr<T>& ptr );

插入 ptr 中存储的指针值到输出流 os 中。

等价于 os << ptr.get()。

参数

os	-	要向其插入 ptr 的 std::basic_ostream
ptr	-	被插入到 os 的数据

返回值

os

示例

运行此代码

#include <iostream>
#include <memory>
 
class Foo {};
 
int main()
{
    auto sp = std::make_shared<Foo>();
    std::cout << sp << std::endl;
    std::cout << sp.get() << std::endl;
}

可能的输出：

0x6d9028
0x6d9028
