# Program 4: Internet Usage Status ## Program Description: Write a Visual C++ program to read Internet usage data from a file and create a report to summarize the data. This program gives you practice with using text files for input and output. You will also use loop algorithms for finding a total, average, and highest value. When you are ready to type in your program, create a new C++ project in Visual Studio using your last name, first initial, and pgm4 as the project name and C++ file name (e.g., `IrvingK_pgm4` and `IrvingK_pgm4.cpp`). Name the report file your program creates `pgm4rpt.txt`. ## Input: Data about each area of the world is stored in a file called `pgm4.txt`. Your program should read in an area name and three numbers representing the population, number of Internet users in 2000, and number of current Internet users for that area. After processing the data for one area, your program should read in the data for the next area, and so on. Copy the file `pgm4.txt` from Canvas into your project folder. The data in the file includes four lines for each area with the area name followed by the three numbers. Assume that you do not know the number of areas ahead of time, so your program should be able to handle any amount of data that may be in the file. Note: Pay attention to the range of integer numbers, you may have to use a long int to hold on some very large numbers contained in this file. The first couple of areas look like this: ``` Africa 1012795909 45943600 138146670 Asia 3843672925 ``` ## Program Processing Steps: 1. **Initialization** - Your program should first open the input file (to read the data from) and an output file (to write the report to) and check the success of each of these operations. Also, do any initialization of variables required and print the headings for your report to the output file. 2. **Use a while loop to:** - **Read in the name, population, and Internet usage values for an area.** - **Print the penetration and growth percentages for the area using the formulas below.** \[ \text{Penetration \%} = \frac{\text{Current Internet Users}}{\text CS2010 - Program 4: Internet Usage Status **Program Description**: Write a Visual C++ program to read in Internet usage data from a file and create a report to summarize the data.
