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 ) ;

ptr に格納されたポインタの値を出力ストリーム os に挿入します。

os << ptr. get ( ) と同等です。

パラメータ

os - ptr を挿入する std::basic_ostream
ptr - os に挿入されるデータ

戻り値

os

例

このコードを実行 
#include <iostream>
#include <memory>
class Foo {};
int main()
{
    auto sp = std::make_shared<Foo>();
    std::cout << sp << '\n';
    std::cout << sp.get() << '\n';
}
