- Write a program that asks the user for the name of a file. The program should display only the first five lines of the file’s contents. If the file contains less than five lines, it should display the file’s entire contents.arrow_forward(C#)Assume inputFile references a StreamReader object that is associated with a file that is already open. Which statement can read all the items in the file without knowing how many items the file contains? Question 9 options: while (!inputFile.EndOfStream) { } while (inputFile.EndOfStream) { } while (inputFile != EndOFStream) { } while (inputFile == EndOfStream) { }arrow_forwardThe standard library function int fseek(FILE *fp, long offset, int origin) is identical to Iseek except that fp is a file pointer instead of a file descriptor and the return value is an int status, not a position. Write fseek. Make sure that your fseek coordinates properly with the buffering done for the other functions of the library.arrow_forward

- Write a function, WriteFile(), that saves information to a text file. The function receives a string value (obtained from Question 3.2) that is written to the text file. The function does not return any value to the calling statement.Store the output text file as Output.txt.The output must be added on a new line to the text file each time without erasing any existing The above functions (ReadFile(), Decode(), and WriteFile()) must now be implemented in the main program in the following order:1. Create a list of type character, i.e. the data type that is stored in the list is text.2. Read the contents of the file to the lists with ReadFile(). Display the number of lines that are read from the text file.3. Decode each card number with the Decode() function by passing the list to the function.4. As each card number is decoded, write the information to an output file with WriteFile(). The WriteFile() function should be called from within the Decode() function.arrow_forwardWrite a statement that defines an fstream object named dataFile and opens afile named salesfigures.txt for input. ( Note: The file should be opened withthe definition statement, not an open function call.)arrow_forwardQ2: Suppose that the file (employee.txt) shown in the figure was stored in the default path, the data stored in this file is employee's name (string), his age (integer), and his salary (double); this data is stored for unknown number of employee.
