Chapter 15, Problem 6PC

Program Plan Intro

Removal of Line Breaks

Program Plan:

• Include the required header files to the program.
• Definition for filter class.
  • In public, declare the function for “do_Filter()”.
  • In protected, declare the function for “transform(char ch)”.
• Include the required function prototypes.
• Function definition of the function “do_Filter()”.
  • Declare the variable "letter" to get the character stored in the file.
  • Loop to check the end of file.
  • Output the characters to the file.
  • Get the character from the input file.
• Derived class “Line_Break”.
  • In protected, define the “transform ()” function.
    • Inside the function return the value to the function.
  • In public, declare the “do_Filter ()” function.
• Definition of “do_Filter ()” function.
  • Check the input file contains the line breaks.
    • If so, removal the line breaks and adds a space between the each word.
    • Otherwise, call the “transform ()” function.
  • Declare the “File_print()” function.
• Define the main() function.
  • Declare the require variable to hold the input and output file.
  • Get the file name from the user.
  • Create an object for the input file.
  • Check the file open condition using “while” loop.
    • Exit the program for invalid filename.
  • Call the function “File_print()”.
  • Get the output file name from the user.
  • Create an object for the output file.
  • Check the file open condition using “while” loop.
    • Exit the program for invalid filename.
  • Creating an object for “Line_Break ()”.
  • Close output file.
  • Re open the file to print the content.
  • Close all files.
• Function definition for the function “File_print()”.
  • Clear the content of the file.
  • Seek arbitrary position in the file.
  • Loop to check the end of file.
    • Print the character.
  • Clear the content of the file.
  • Seek arbitrary position in the file
