To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
There is not much substance in this book. It does not go through how to perform common tasks needed in setting up a Project from scratch and how to do things like important libraries, setup header and linked files to link to files in your project, create copies of a project without losing links, how to create a Make file from scratch and use it. Etc.
