Using your source code from Update #3 of the Real Estate Commissions program, do the following: 1. Create a file in Notepad that contains your test data excluding the bad data. (Note: We are assuming the file has been checked for errors and that the remaining data is good dataso basically the data from Update # 2 Be sure to press the Enter key after the last record is typed into Notepad. Save the file with a .txt or .dat file extension. 2. Read the test data from the file created in Step 2. 3. Instead of, or in addition to writing the output to the screen, send the output to a file. Test your program using your input file.
