Processing requirements $-$ Display City Map

Realistically, there is limited graphical display capabilities available when you are constrained to displaying output on Ubuntu shell's terminal. Figure B$-3$ below illustrates the actual display formatting requirements when user selects the "Display City Map" option from your program's menu.

Fig. B$-3$

Note :

$($i$)$

The city id is displayed on the relevant grid areas, instead of city names!

$($ii$)$

Refer to Fig. B$-1,$ which describes how each city's id value is stored in the input file

$($iii$)$

The entire extent of the map is bounded by the $\text{'}$#$\text{'}$ char $!$

a$)$ As discussed in earlier Appendix A$,$ Fig. A$-1,$ the range values for variables 'GridX$\_$IdxRange' and 'GridY$\_$IdxRange' can vary.

This implies the size and shape of your map display can change as well $($e$.$g$.$ it is possible to have a large 'rectangular' shaped grid$-$area map! $).$

Therefore, please do not assume $/$ "hard code" any constant values for your array sizes to store your map data!

b$)$ You must make use of basic $C++$ array, and dynamic memory allocation $($ research on how to use 'new' $)$ to initialize the size of your arrays during program runtime, to store all relevant weather map data.

c$)$ The type of the array $($e$.$g$.$ int, double, struct, etc$)$ is up to you, and there is no restriction on how many arrays you think is necessary to store all the relevant weather data.

d$)$ Before your program exit, you must deallocate all memory that was dynamically allocated by you during runtime $($ research on how to use 'delete' $).$ Failure to do so results in memory leak $...$ and marks deduction!
