Problem 1 - Retail Price Calculator

You must create a program that can read in a series of values representing the wholesale cost of items and calculating the total retail price value of all those wholesale prices. Retail price is calculated as a percentage of the wholesale price plus the original wholesale price.

The following rules apply to marking up a price of an item:

If an item's wholesale cost is less than $100, its markup percentage is 100%. An item that costs $5.00 would cost $10.00.

If an item's wholesale cost is greater than or equal to $100, its markup percentage is 50%. An item that costs $150 would cost $225.00.

The program must have a method named CalculateRetail that receives the wholesale cost and returns the retail price of the item

The input will come from a text file containing 10 or more random currency values with one value on each line

The output is the total price (wholesale cost + markup) for all the prices in the file and that value is displayed on the form

The input file must be selected using an Open File Dialog

Here is a sample input file

    public partial class frmMain : Form
    {
        public frmMain()
        {
            InitializeComponent();
        }

        private void btnGo_Click(object sender, EventArgs e)
        {
            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {
                if (saveFileDialog.ShowDialog() == DialogResult.OK)
                {
                    StreamReader inputFile;
                    inputFile = File.OpenText(openFileDialog.FileName);
                    StreamWriter outputFile;
                    outputFile = File.CreateText(saveFileDialog.FileName);
                    while (!inputFile.EndOfStream)
                    {
                        // read a line of the input file
                        // call the IsPrime method to decide whether or not the number is prime
                        // if the result is that the number is prime, write to the output file using the specified format
                        // if the result is that the number is not prime, write to the output file using the specified format
                    }
                    outputFile.Close();
                    inputFile.Close();
                }
            }
        }
    }
}

You must create a program that can read in a series of integers as input from a text file and output a text file documenting whether or not for each of the values in the input file the number is or is not prime. See question 8 of Chapter 6 on page 387 for more tips on performing that calculation.

The program must have a method called IsPrime that takes an integer as an argument and returns true if the argument is a prime number and false otherwise

The input will come from a text file containing 10 or more random integer values with one value on each line

The output of the program will be a text file that for each line displays the input integer and whether or not it is prime

Each line of the output file will follow this format: [Input] - [IsPrime/NotPrime]

Here is a sample output file corresponding to this sample input file

(input file)

The input file must be selected with an Open File Dialog

The output file must be selected with a Save File Dialog
