What type of object do you create if you want to read data from a text file?

(Inventory) Create an ASCII file with the following data, or use the shipped.dat file available on this book’s Web site. The headings aren’t part of the file but indicate what the data represents Using this data file, write a C++ program that reads the file and produces a report listing the shipped date, part number, first name, last name, and company name.

(Data processing) Write a C++ program that allows the user to enter the following information from the keyboard for each student in a class (up to 20 students): Name Exam 1 Grade Exam 2 Grade Homework Grade Final Exam Grade For each student, your program should first calculate a final grade, using this formula: FinalGrade=0.20Exam1+0.20Exam2+0.35Homework+0.25FinalExam Then assign a letter grade on the basis of 90100=A,8089=B,7079=C,6069=D, and less than 60=F . All the information, including the final grade and the letter grade, should then be displayed and written to a file.

Create a program named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a files size, you can create a System. 10. Filelnfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length;

Open the Calories Solution.sln file contained in the VB2017\Chap08\Calories Solution folder. Open the Code Editor window and locate the btnDisplay_Click procedure. The procedure declares and initializes a one-dimensional array named intCalories. The array stores the numbers of daily calories consumed. The procedure should calculate and display the average number of calories consumed; use the Math.Round method to round the average to an integer. (You learned about the Math.Round method in Chapter 6.) The procedure should also display the number of days in which the daily calories were greater than the average, the number of days in which the daily calories were the same as the average, and the number of days in which the daily calories were less than the average. Code the procedure. Save the solution and then start and test the application.

(Misc. application) Four experiments are performed, and each experiment has six test results. The results for each experiment are given in the following list. Write a program using a nested loop to compute and display the average of the test results for each experiment. 1stexperimentresults:23.23116.92725.428.62ndexperimentresults:34.845.227.936.833.439.43rdexperimentresults:19.416.810.220.818.913.44thexperimentresults:36.93949.245.142.750.6

(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.

The intSales array is declared as follows: Dim intSales() As Integer = {10000, 12000, 900, 500, 20000}. The statement intSales (2) += 10 will _____. replace the 900 amount with 10 replace the 900 amount with 910 replace the 12000 amount with 10 replace the 12000 amount with 12010

(Numerical) Write and test a function that returns the position of the largest and smallest values in an array of double-precision numbers.

For each of the following exercises, you may choose to write a console-based or GUI application, or both. Write a program named TestScoreList that accepts eight int values representing student test scores. Display each of the values along with a message that indicates how far it is from the average.
