[modifier] Exemple
#include <iostream> #include <memory> int main() { std::unique_ptr<int> p1(new int(42)); std::unique_ptr<int> p2(new int(42)); std::cout << "p1 == p1: " << (p1 == p1) << '\n'; // p1 and p2 point to different memory locations, so p1 != p2 std::cout << "p1 == p2: " << (p1 == p2) << '\n'; }
Résultat :
p1 == p1: 1 p1 == p2: 0
