I explain how to use Google Benchmark library to measure the runtime and benchmark your C++ code.

I show how to sweep the input parameters to your functions and see how the runtime changes. Also, I cover how to estimate the runtime complexity of an algorithm using this library and calculate the coefficient of the highest term in the runtime complexity expression in Bog-O notation.

As an example of benchmarking, I compare Binary Search algorithm to Ternary Search, Exponential Search and Multi Threaded Binary Search.

You can quickly set up and use Google benchmark by downloading my repo from here:
