HDF5 is a highly efficient file format for storing datasets and scientific values. The HighFive library provides a higher-level C++ interface for the C library provided by the HDF Group. In this example, we propose to look at its interface by transforming the dataset used in the previous section to HDF5 format.
The main concepts of HDF5 format are groups and datasets. Each group can contain other groups and have attributes of different types. Also, each group can contain a set of dataset entries. Each dataset is a multidimensional array of values of the same type, which also can have attributes of different types.
Let's start with including required headers, as follows:
#include <highfive/H5DataSet.hpp> ...
