a.

Program Plan Intro

Program Plan:

  • Include library files for various operations.
  • Declare object ofofstream.
  • Create a statement to open the write data to the file “employee.dat”.
  • Use if statement with fail() method to check that the entered file name is available or not.
  • int main() function is used to perform all the task.
  • Display the calculated results to the user.

Program Description: The main purpose of the program is to create a text file, “employee.dat” and to write the given data to the file.

b.

Program Plan Intro

Program Plan:

  • Include library files for various operations.
  • Declare objects ofifstream and ofstream.
  • Declare required variable.
  • Create two statements to open “employee.dat” and “employee.bak” file.
  • Use if statement with fail() method to check that the entered file name is available or not.
  • int main() function is used to perform all the task.
  • Display the calculated results to the user.

Program Description: The main purpose of the program is to modify the program code of part (a) so that the program code can create a duplicate copy of the text file with the name “employee.bak”, that contains all the data of “employee.dat” file.

Program Plan Intro

Program Plan:

  • Include library files for various operations.
  • Declare objects ofifstream and ofstream.
  • Declare required variable.
  • Read file names from the user.
  • Create two statements to open “employee.dat” and “employee.bak” file.
  • Use if statement with fail() method to check that the entered file name is available or not.
  • int main() function is used to perform all the task.
  • Display the calculated results to the user.

Program Description: The main purpose of the program is to modify the program code of part (b)so that the program code will read the name of the original and duplicate file from the user, creates a duplicate copy of the text file with name “employee.bak”, that contains all the data of “employee.dat” file.

(C ONLY) The program expects the name of an input file and an output file to be given by the user. If the user does not input any names, default file names should be used, such as input.txt and output.txt. The input files have lines which look like this: 3 Tester College; 1909 33001 The first number represents the rank; it is followed by the school name, year founded, and approximate number of students. Read the list of colleges into an array of structures. You may assume that the maximum size of a college name string is 64. The program should use either the insertion sort algorithm or the selection sort algorithm to sort the array in descending order by rank. Display any k consecutive schools requested by the user. For instance, if the user enters 12, the program displays the first 2 schools in a readable format of your choice. If the user enters 15, the program displays the first five schools, if the user enters 2 7, display 7 schools beginning with the one at index 1 (2 - 1), and so…
(C Language) Given a set of text files containing synonyms for different words, complete the main program to output the synonyms for a specific word. Each text file contains synonyms for the word specified in the file’s name, and the synonyms within the file are grouped according to the synonyms' first letters, separated by an '*'. The program reads a word and a letter from the user and opens the text file associated with the input word. The program then stores the contents of the text file into a two-dimensional array of char* predefined in the program. Finally the program searches the array and outputs all the synonyms that begin with the input letter, one synonym per line, or a message if no synonyms that begin with the input letter are found.
(python) Write a function sum_file(f) that takes a filename f. Each line in f contains a single number. You should write to the last line in the file the sum of all the numbers written in the file.
