I need help writing a C++ code to store and print a list of bottles. The instruction as follows:
If you wish, please comment on each code line so I can learn from your thought process.
Thank you!
Here is an example output
Store and print a list of bottles that is part of someone's collection. You will get the list of bottles from a text file. I've provided a couple text files for you. We will grade with big.txt. Your text file reading doesn't need to be fancy. The data is space delimited. There is a maximum of 30 records in the file. Make and use a constant for this. You may use the string class for any text variables. Use functions and methods in a logical way. Don't have big functions or methods. Your classes and structures must: Each have their own.h and.cpp. Only methods that are 1 line may be inline in the.h) Be const correct. Don't underestimate the work of this the first-time round. (It will be easier if you make it a habit and just start const correct.) Your.h must either use #ifndef or #pragma once. If you use #pragma once you must provide a comment that describe how it works and demonstrates that you understand it. Note: Since you are adding.h and.cpp for your classes you will be pushing new files to github. You can do it! You will have at least 1 class to store the information about a single bottle. The information we care about is: The color-One word to describe the color. The type-One word to describe the type of bottle: i.e. flask, syrup. The age - an integer to indicate how old the bottle is. The value-a double to indicate how much the bottle is worth. To stay const correct you will need getter functions for all the data. Thes functions can be defined in the.h since they will only be a line long. A print method that prints a single bottle. A default constructor that blanks or zeros all the data. A constructor that takes all 4 pieces of data (color, type, age, value) and calls the initialization function below. You will need setters for all your data or a method to initialize a whole bottle. As a hint here is the signature from mine: void init (const string & color, const string & cat, int age, double value); You will have another class or structure to represent the collection of bottles. You will fill the collection as you read the file and add bottles. It has the following member data. An array for your bottles. It is at most 30 bottles (see note above about file size.) An integer to indicate how many bottles you have at this moment. (So, for example the test.txt file has 7 as the size. A method to provide the total value of the collection. This will simply loop through the array of bottles and sum the values. A method to print the collection. It will also print the count of bottles and the total value. Note that I said you can do this as a structure. You can also do it as a class with private member data. If you do this, you can get some extra credit because this will be harder. I strongly suggest that you get it to work as a structure before adding the private member data. (Also, I'd suggest moving one piece of data to private at a time to limit your exposure to errors.) Please do this incrementally. In the program, I added comments with most of the steps that I did. My steps are only a suggestion. Your steps will likely be smaller as this is your first time at classes. Just do a small bit and compile and test. Output Here is an example of the output from my program for test.txt. You don't have to copy it exactly. Just be self-documenting and not ugly.
