C++ System Programming Cookbook

How it works...

Step 1 takes care of including the headers we'll need later: <iostream> for the standard output and <vector> and <chrono> for the time.

Step 2 defines a vector of int called elements. Due to this, we can call the now() method on the system_clock class in the chrono namespace to get the current time. Although we used auto, this method returns a time_point object representing a point in time. Then, we looped over 100 million times to populate the elements array in order to highlight that we used the new C++14 feature to represent 100,000,000, which improves the readability of the code. At the end, we took another point in time by calling the now() method and storing the time_point object in the end variable.

In step 3, we looked ...
