std::shared$\_$ptr is used for shared$-$ownership resource management. Given the following function definition:

template

void Foo$($std::shared$\_$ptr sp$)\{$

std::cout $<<$ sp$.$use$\_$count$()<<$ std::endl;

$\}$

What will Foo have written to standard output after the following statements have executed?

auto m$1=$ std::make$\_$shared$(7)$;

Foo$($m$1)$;

Note: a shared$\_$ptr$\text{'}$s use$\_$count returns the number $($i$.$e$.,$ count$)$ of shared$\_$ptr objects engaged shared ownership of the resource pointed to$.$
