Data Processing Sample

Tasks

Write a program to read product inventory data from a data file here and display in web page format. The data processing tasks include:

1. Write a C++ program to read wine inventory data from the input file line by line (each line represents a wine indventory)
2. Output the data into a HTML file in tabular format using HTML table tags. A sample of output file is here
3. View the HTML file in web browser to check if your program reads and outputs data correctly
4. Calculate inventory value for each product (= Units in Stock x Unit Price) and sum them as the total inventory value of all products
5. Find out which product (product name) has the most inventory value and its inventory value. A procedure of finding the max value among a list of numbers is given below:
   • Define a float variable named max for storing the max inventory value among all products
   • Assume the inventory value of the first product is the max initially
   • Use a loop to check each of the remaining products. If the inventory value of the product currently being checked is greater than max, update max with it. Otherwise, ignore it and keep going until all products are checked.
   • Upon the completion of the looping, max store the max inventory value among all products.
   • To record product name with most inventory value, you need to define a string type variable, say, pName. Whenever the value of variable max is updated, pName needs to be updated with the product name as well.

     //Sample code
     
     ifstream inData;
     ofstream outData;
     inData.open("OrderData.txt");
     outData.open("inventory.html");
     
     //Print table header
     outData << "<table border=1>" << endl;
     
     //Read the first product
     inData >> ...
     while(inData)
     {
        //Processing data including printing a table row for each product
        //...
        
        //Read next product
        inData >> ...
     }
     outData << "</table>" << endl;
     

6. If you want to add a remote stylesheet file, feel free to do so. Below is an example of remote stylesheet:

   <link rel="stylesheet" href="https://cscdevprod03.txwes.edu/~yzhang/css/course.css" type="text/css">
   

   Note that when putting the link in C++ output statements, make sure to add backward slashes "\" in front of those double quotes inside the link tag to distinguish C++ string double quotes.

What to submit

Submit both C++ program and HTML output file to Blackboard by the midnight of the due day.
