cpp_unique_ptr_in_vector.cpp

#include <iostream>
#include <memory>
#include <vector>

struct Test {
    Test(int data = 0) : data(data) {
        std::cout << "Test::Constructor: " << this->data << std::endl;
    }
    ~Test() {
        std::cout << "Test::Destructor: " << this->data << std::endl;
    }
    int data;
};


int main()
{
    std::vector<std::unique_ptr<Test>> vec;

    for(int i = 0; i < 5; ++i) {
        vec.push_back(
            std::unique_ptr<Test>(new Test(i)));
    }

    for(auto &elem : vec) {
        std::cout << elem->data << std::endl;
    }

    return 0;
