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 );

Inserts the value of the pointer stored in ptr into the output stream os.

Equivalent to os << ptr.get().

Parameters

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

Return value

os

Example

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
