Modify this c++ code which calculated the wind chill factor and cloud base altitude from inputs of temperature, wind speed, and the dew point, to read the values from a file called weatherData.txt. Read the values, compute the results, and write the results to a file called yourName.txt and also display them on the output console. The data sentinel is -99.

The program must have at least four (4) functions: one for opening the files with file failure conditions, one to compute the wind chill, one to compute the cloud base, and at least one for the output. Consider other functions as you see fit.

Main will close the files before returning zero.

The input and output streams can be declared globally.

(Try not to use global variables)

The program must read the data from the data file weatherData.txt.

The program must produce the required output to the console window and to a file.

The output must be as shown in the screen capture below (notice the extra note shown).

The equations for the wind chill factor and computing cloud base are in the previous instructions.

The equation for approximating the wind chill factor in North America is:

w_c = 35.74 + 0.6215 * T_a - 35.75 * V^0.16 + 0.4275 * T_a * V^0.16

The cloud base in feet above ground level is determined by the "spread" which is the difference between the temperature and the dew point, and is calculated:

cloudBase = temperature_spread / 4.4 * 1000;

Note: When the input does not produce a valid wind chill value, the program will need to retain this information to output the required text.

Output Formatting for the display and output file are to be exactly as shown below.
