/And these following needs to be incorporated into it. Any help would be appreciated. In C++.Thank you

Your class implementation from Lab #10 should have at least these fields, with setters and getters for all:

name

rating

numInstalls

numReviews

price

Assignment:

The supplied file - apps.csvPreview the document - has a list of 25 actual Google Play apps in a common file format called CSV (Comma-Separated Values). This is a text file that has a series of lines representing rows and columns. Each line is a row with a series of column values, separated by a comma (,). The order of the fields in the file is as follows:

name, category, rating, numInstalls, numReviews, price

All of these fields should be in your googlePlayApp class already, except for category, which should be a string. Add that field to the class and the constructor with arguments, including setters/getters.

We will review an example way of processing a CSV file in class.

Read the supplied CSV file as input with one app. per line, and store each entry in a dynamic structure (a dynamic array -- not a fixed-size array -- or a vector). Each class should be allocated based on a single line in the file.

After the file has been read, go into an "app directory" loop and prompt the user for an application name. If there is a match for that name in the list, print out that the information for that app.

Requirements:

1) The CSV file must be read as input and any app. should be queryable. No hard-coded arrays of strings, etc. will be accepted.

2) Allocate each googlePlayApp dynamically based on each entry in the file.

3) Use any search algorithm to find the name. Linear search (walking through the array, checking for a match, until the end or a match is found) is OK.

4) Print all of the info about the app (the above fields, including category, and the special formatting of 'price') using the 'getter' methods.

5) If the user enters a name that is not found, output 'Name not found' or similar. Continue in the loop until some sentinel value is read (such as a blank line, or an 'X', etc.), then exit.
