/* This programs measures the time a certain function takes to be executed. The result can be used to figure out which langugage feature or library works faster. If you try it in the code playground you may get a 'time limit exceeded' error. To fix this you can reduce the execution time for example by using less loops in the test function. Often it also helps to run it twice. Leave a like if you enjoyed. Feel free to use this code in your own programs. Btw. if you create similar programs in other languages we could compare the speed of different languages. For more accurate results you should probably execute this code on your personal device and not in the playground. */ #include #include #define hrc high_resolution_clock using namespace std; using namespace std::chrono; void benchmark() { // - - - - REPLACE HERE - - - - unsigned long c = 0; for(unsigned long t = 0; t != 700000000; t++) { c++; } // - - - - - - - - - - - - - - - } int main() { hrc::time_point start_time, end_time; start_time = hrc::now(); benchmark(); end_time = hrc::now(); long duration = long(duration_cast( end_time - start_time).count()); //calculating the time spent for the benchmark cout << "---------------------------\n"; cout << " Time in micros: " << duration; cout << "\n---------------------------\n"; cout << " Time in millis: " << float(duration) / 1000; cout << "\n---------------------------\n"; cout << " Time in seconds: " << float(duration) / 1000000; cout << "\n---------------------------\n"; cout << "\nEdit the code and run your own benchmark!\n\n"; cout << "NOTE: This code runs in the playground but not on your personal device.
