How does share_ptr release memory when main ends?

It is said that this is related to threads, I don't know much about OS.Thanks for your Answers.

int main(){
    shared_ptr<int> p = make_shared<int>(1024);
    //do nothing,end my program
}

use_count() will be 1 if I check in main，how to be 0？Or wo need to release operation.

Nothing to do with the OS, the shared_ptr destructor frees the memory and since p is a local variable the scope will end (i.e call destructor) when main ends.
