Function_______________ is generally used to write data to a random-access file.
Step by step
Solved in 2 steps
- (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.(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.Function ____________opens a file.
- INSTRUCTION: C++ Language Create a function that writes to a file named Inventy.txt the information of 8 items. Ask the user for the item's name, the item's quantity in storage, and the item's price and write it to the file. Create a function that reads the file and items' quantity and price to two different arrays. Create a function that computes the subtotal of each item. Implement all functions inside the main program and the computed value should be displayed with the item's name.Function_____________ reads a character from a specified fileFunction___________ repositions the file position pointer to the beginning of the file
- Function ________repositions the file position pointer to a specific location in the fileThe _______-file stream data type is for input files.Array/File FunctionsWrite a function named arrayToFile. The function should accept three arguments:the name of a file, a pointer to an int array, and the size of the array. The functionshould open the specified file in binary mode, write the contents of the array to the file,and then close the file.Write another function named fileToArray. This function should accept three arguments: the name of a file, a pointer to an int array, and the size of the array. Thefunction should open the specified file in binary mode, read its contents into the array,and then close the file.Write a complete program that demonstrates these functions by using the arrayToFilefunction to write an array to a file, and then using the fileToArray function to readthe data from the same file. After the data are read from the file into the array, displaythe array’s contents on the screen.
- Fill-in-the-Blank The __________ operator is used to dynamically allocate memory.Variables declared in a block or in the parameter list of a function are assumed to be of storage class______________________ unless specified otherwise.Fill-in-the-Blank The __________ member function reads “raw” binary data from a file.
