Say we have a struct of an int array, a float array etc. and we need to write them into a binary format file for fast reloading. Can this be done in a simple way?
Should the files be several for each of the array?

Unless you have a huge amount of data, just write a standard text format. If you can assume c99 on both ends, use the
%aformatter for floating-point data to insulate yourselves from the vagaries of binary-decimal conversion.If the amount of data is huge, or you need to use a “raw data” format for other reasons, you will want to convert your data into a known endianness before writing, and convert back to the host endianness after reading. Any reasonably sane OS has library routines for doing these conversions.
