# SD1.2.5.1.2 NetCDF C++ API The NetCDF-4 C++ API was for using in managing fusion research data from CCFE's innovative MAST (Mega Amp Spherical Tokamak) experiment. The API is implemented as a layer over the NetCDF-4 C interface, which means bug fixes and performance enhancements in the C interface will be immediately available to C++ developers as well. ## Learning Outcomes * Write a two-dimensional array of sample data and read data from this file. * Write some variables with units attributes and coordinate dimensions and read data variables and attributes from this file. * Write some four-dimensional variables using a record dimension and read from the variables from this file.
