APPENDIX A Processing Configuration File Info Upon startup program should prompt user for the following Please enter config filename: config.txt When user presses 'Enter', the program should perform File I/O to read in the contents in the stated filename (eg in this case 'config.txt") The config.txt contains data like size of grid-map area (indicated by index-ranges), as well as a series of filenames, which your program should further access, in order to read in the various relevant weather data provided by the Meteorological Station. Figure A-1 below provides a sample of the actual contents within this configuration file. // The range of 'horizontal' indices, inclusive // E.g. if the range is 0-4, then the indices are 0, 1, 2, 3, 4 Gridx_IdxRange=0-8 // The range of 'vertical' indices, inclusive // E.g. if the range is 0-3, then the indices are 0, 1, 2, 3 GridY_IdxRange=0-8 // {x,y] grid-areas which are occupied by cities citylocation.txt // "next day" forecasted cloud coverage (8) for // each (x,y) grid-area cloudcover.txt // "next day" forecasted atmospheric pressure intensity (%) for // each (x,y) grid-area pressure.txt Fig. A-1 Note : The ranges for both 'Gridx_IdxRange' and 'GridY_IdxRange' will determine the size of the display map. The ranges' values are editable! Regarding the interpretation of each input files' data format, please refer to subsequent Appendices
