MAX_ARRAY_LENGTH<\/code> is a constant defining the maximum number of months that can be placed in the arrays.<\/p>\n
>><\/code> returns a reference to the stream being read so you can chain the operations together and take advantage of the stream’s operator bool<\/code><\/a> when done reading. operator bool<\/code> will return true if the stream is still in a good state.<\/p>\n
The logic looks like<\/p>\n
loop\nif array has room\n    read all required data from stream\n    if all data read\n        increment size\n        go to loop.\n<\/code><\/pre>\n
You may want a test after end of the loop to make sure all of the data was read. If you’re reading to the end of the file, something like if (file.eof())<\/code> will make sure the whole file was read. If you want a year’s worth of data, if (size == ONE_YEAR)<\/code> where ONE_YEAR<\/code> is a constant defining the number of months in a year.<\/p>\n<\/p><\/div>\n
