Question

Hi im having trouble with this homework question. Can someone show me how to do this in C++ with all the steps?

Weather Analysis WeatherAnalyzer - New Day Data 2- Good Days 3- Summary 0- Exit Step 0: You can get the sample file from this link: Each row in the text file represent weather measurement of a day. For each day, the file contains the temperature (first column), humidity (second column) and the wind (third column) values emp 70 Humidity: 50 Weather Analysis 1- New Day Data 2- Good Days 3- Summary Create a class with 3 fields and read the data into an array of objects. [60] Min. Desired Temp.: 60 Max. Desired Temp. 85 There were 17 good days wavg. temp 65.2941. user to add a new reading using the Feature 1: In addition to the file, allow Weather Analysis program. Make sure that none of the values (temp. humidity or wind) user enters is greater than 120 or less than 0. If so, give warning and do not add the data. Otherwise add the new data to the 1- New Day Data 2- Good Days 3- Summary 3 ataset contains 61 days of data. Lowest: array of objects. [80] Feature 2: We want to know how many good weather days we have in the data set. Ask user for a desired comfort emp. 60F Humidity: 40% Wind: 10MPH Highest Temp.: 70F Humidity: 50% Wind: 19MPH temperature range and count and report the number of days where the temp is within this specified range AND humidity is between 40% to 70% (exclusive) AND wind is less than 12MPH. Make sure to Weather Analysis include the average temperature during those days [70] 1- New Day Data 2- Good Days Summary Feature 3: This basically computes and reports the lowest and highest temp. Humidity and wind in the data set. [70] Press any key to continue. Feature 0: Exit the program. [20] The data looks like integers, but you may want to use double data type as it will make things much easier for you during calculations Make sure to use prototypes. [-30] Make sure that you can both read and save the file [-30] Make sure to comment your code and use proper indentation. [-50] Make sure to use functions -each feature should be implemented in its own function. [-50] No global variables allowed. [-60] Hints and Penalties

Here is the code :
