std::shared_ptr::get(3)

NAME
std::shared_ptr::get - std::shared_ptr::get

Synopsis
   T* get() const noexcept; (until C++17)
   element_type* get() const noexcept; (since C++17)
   Returns the stored pointer.

Parameters
   (none)

Return value
   The stored pointer.

Notes
   A shared_ptr may share ownership of an object while storing a pointer to another
   object. get() returns the stored pointer, not the managed pointer.

Example
// Run this code
 #include <iostream>
 #include <memory>
 #include <string_view>
 int main()
 {
     auto output = [](std::string_view msg, int const* pInt)
     {
         std::cout << msg << *pInt << " in " << pInt << '\n';
     };
     int* pInt = new int(42);
     std::shared_ptr<int> pShared = std::make_shared<int>(42);
     output("Naked pointer: ", pInt);
 // output("Shared pointer: ", pShared); // compiler error
     output("Shared pointer: ", &*pShared); // OK, calls operator*, then takes addr
     output("Shared pointer with get(): ", pShared.get());
     delete pInt;
     std::cout << "\nThe shared_ptr's aliasing constructor demo.\n";
     struct Base1 { int i1{}; };
     struct Base2 { int i2{}; };
     struct Derived : Base1, Base2 { int i3{}; };
     std::shared_ptr<Derived> p(new Derived());
     std::shared_ptr<Base2> q(p, static_cast<Base2*>(p.get()));
     std::cout << "q shares ownership with p, but points to Base2 subobject:\n"
               << "p.get(): " << p.get() << '\n'
               << "q.get(): " << q.get() << '\n'
               << "&(p->i1): " << &(p->i1) << '\n'
               << "&(p->i2): " << &(p->i2) << '\n'
               << "&(p->i3): " << &(p->i3) << '\n'
               << "&(q->i2): " << &(q->i2) << '\n';
 }

Possible output:
 Naked pointer: 42 in 0xacac20
 Shared pointer: 42 in 0xacac50
 Shared pointer with get(): 42 in 0xacac50
 The shared_ptr's aliasing constructor demo.
 q shares ownership with p, but points to Base2 subobject:
 p.get(): 0xacac20
 q.get(): 0xacac24
 &(p->i1): 0xacac20
 &(p->i2): 0xacac24
 &(p->i3): 0xacac28
 &(q->i2): 0xacac24
