Write a console program in a module named Weather with a Main subroutine that reads an input file of temperatures, with real numbers representing daily high temperatures such as:
16.2 23.2
19.2 7.7 22.9
18.4 -1.6 14.6
Your program should prompt for the file name to read, then read its data and print the change in temperature between each pair of neighboring days.
Input file? weather.txt
16.2 to 23.2, change = 7.0
23.2 to 19.2, change = -4.0
19.2 to 7.7, change = -11.5
7.7 to 22.9, change = 15.2
22.9 to 18.4, change = -4.5
18.4 to -1.6, change = -20.0
-1.6 to 14.6, change = 16.2
You may assume that the user types the name of a file that exists and is readable.
You may also assume that there are not any non-numeric tokens of input in the file.
