int main() {
auto start = std::chrono::steady_clock::now();
std::cout << "Hello World\n";
auto end = std::chrono::steady_clock::now();
std::cout << "Printing took "
// duration_cast is required to avoid accidentally losing
precision.
<< std::chrono::duration_cast<std::chrono::microseconds>(end -
start).count()
<< "us.\n";
}
