/* Hi guys, this code is not working in the code playground. Any thoughts on how to fix this? Please lmk in the comments. Code works perfectly fine in Visual Studio 2019 Container benchmarking using chrono. How does the 'swap' operation perform on different containers? Let's find out! Note: for more reliable results, run this code multiple times. :P */ #include #include #include #include #include #include #include using namespace std::literals::chrono_literals; struct Timer { std::chrono::time_point start, end; std::string name; std::chrono::duration duration; Timer() : start(std::chrono::high_resolution_clock::now()), name("Timer"), duration(0) {} //DEFAULT Constructor Timer(std::string name) : start(std::chrono::high_resolution_clock::now()), name(name), duration(0) {} //Constructor ~Timer() { print(); } void print() { end = std::chrono::high_resolution_clock::now(); duration = end - start; float ms = duration.count() * 1000.f; std::cout << name << " took " << ms << " ms\n"; } void pause(std::chrono::milliseconds a) { std::this_thread::sleep_for(a); start += a; } }; int main() { { Timer a("Vec"); std::vectorvec = { 1,2,3,4,5,6,7 }; std::vectorvec2 = { 8,9,10,11,12,13,14 }; vec.swap(vec2); } { Timer b("Arr"); std::array arr = { 1,2,3,4,5,6,7 }; std::arrayarr2 = { 8,9,10,11,12,13,14 }; arr.swap(arr2); } { Timer c("List"); std::list li = { 1,2,3,4,5,6,7 }; std::listli2 = { 8,9,10,11,12,13,14 }; li.swap(li2); } }
