Timing sections of your code and showing the results

Our new Timer class uses the C++ chrono library, a specialized part of C++ dealing with clocks, durations, and points in time.

You can find the example code of this section in the 03_opengl_ui_timer and 07_vulkan_ui_timer folders.

Adding the Timer class

Create the new Timer class by adding the Timer.h file in the tools folder:

#pragma once #include <chrono>

After the header guard, we include the chrono header. The elements from the chrono header can be found in the std::chrono namespace.

Next, add the Timer class itself in the Timer.h file:

class Timer {   public:     void start();     float stop();   private:     bool mRunning = false;     std::chrono::time_point<std::chrono::steady_clock>       mStartTime{}; };

The Timer class has two public methods: the start() method...
