(Data processing) Write a C++ program that reads the file created in Exercise 4, permits the user to change the hourly wage or years for any employee, and creates a new updated 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) 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.
Write a program to implement the algorithm that you designed in Exercise 22 of Chapter 1. (Assume that the account balance is stored in the file Ch4_Ex15_Data.txt.) Your program should output account balance before and after withdrawal and service charges. Also save the account balance after withdrawal in the file Ch4_Ex15_Output.txt.
(Practice) a. Write a set of two statements declaring the following objects as ifstream objects, and then opening them as text input files: inData.txt, prices.txt, coupons.dat, and exper.dat. b. Rewrite the two statements for Exercise 2a, using a single statement.
(Data processing) a. Store the following data in a file, or use the numbers.dat file provided on this book’s Web site. 5 96 87 78 93 21 4 92 82 85 87 6 72 69 85 75 81 73 b. Write a C++ program to calculate and display the average of each group of numbers in the file created in Exercise 2a. The data is arranged in the file so that each group of numbers is preceded by the number of data items in the group. Therefore, the first number in the file, 5, indicates that the next five numbers should be grouped together. The number 4 indicates that the following four numbers are a group, and the 6 indicates that the last six numbers are a group. (Hint: Use a nested loop. The outer loop should terminate when the end of file has been encountered.)
(Data processing) Write a C++ program that reads the file created in Exercise 4 one record at a time, asks for the number of hours each employee worked each month, and calculates and displays each employee’s total pay for the month.
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;
(File creation) Write a C++ program that creates an array containing the integer numbers 60, 40, 80, 90, 120, 150, 130, 160, 170, and 200. Your program should then write the data in the array to a text file. (Alternatively, you can create the file with a text editor.)
Each of the following files in the Chapter.05 folder of your downloadable student files has syntax and/or logical errors. In each case, determine the problem, and fix the program. After you correct the errors, save each file using the same filename preceded with Fixed. For example, save DebugFive1.cs as FixedDebugFive1 .cs. a. DebugFive1.cs b. DebugFive2.cs c. DebugFive3.cs d. DebugFive4.cs
(Data processing) a. Write a C++ program that opens a file and displays its contents with line numbers. That is, the program should print the number 1 before displaying the first line, print the number 2 before displaying the second line, and so on for each line in the file. b. Modify the program written in Exercise 6a to list the file’s contents on the printer assigned to your computer.
Write a program that reads in a line consisting of a students name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1.
