std::shared...::operator<<(3)

🌸 NAME 🌸

std::shared_ptr::operator<< — std::shared_ptr::operator<< 💅

okay so this is the C++ Standard Libary manual page for the stream-insertion operator that works with std::shared_ptr, and it's literally here to help you understand what happens when you send one into an output stream ✨

---

✨ Synopsis ✨

bestie, here's the signature — keep it exact, no cap:

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 );

what it does: it inserts the value of the pointer stored in ptr into the output stream os 🫶

it's equivalent to os << ptr.get() — periodt 🌟

---

🎀 Parameters 🎀

• os — a std::basic_ostream to insert ptr into
• ptr — the data to be inserted into os

---

💖 Return value 💖

it returns os 💖

---

🦋 Example 🦋

run this code, it's giving shared-pointer-in-a-stream realness:

// Run this code

#include <iostream>
#include <memory>

class Foo {};

int main()
{
    auto sp = std::make_shared<Foo>();
    std::cout << sp << '\n';
    std::cout << sp.get() << '\n';
}

🌟 Possible output 🌟

0x6d9028
0x6d9028
