Working on a function in C where I have an file of forbidden

Working on a function in C++ where I have an file of \"forbidden words\" loaded into an unordered_set, using an input file I want to parse through each line of the file using the getline() command and remove any instance of \"forbidden words\" found within the getline() string.

How would I remove an instance of a \"forbidden word\" that is located within the string from getline()?

Solution

/*
   A file is a collection of related data stored in a particular
   area on the disk.

   A program typically involves either or both of the following
   kinds of data communication:

   1. Data transfer between the console unit and the program
   2. Data transfer between the program and a disk file.

   File stream classes
   -------------------
   filebuf-> Its is used to set the file buffers to read and write.

   fstreambase-> Provides operations common to the file streams.
           Serves as a base for fstream,ifstream and ofstream
           classes.
   ifstream-> Provides input operations.Contains open() with default
       input mode. Inherits the functions get(),
       getline(),read(),seekg() and tellg() functions from
       istream.
   ofstream-> Provides output operations. Contains open() with
       default output mode. Inherits put(), seekp(),
       tellp(), and write() functions from ostream.
   fstream-> Provides support for simultaneous input and output
       operations Contains open() with default input mode.
       Inherits all the functions from istream and ostream
       classes through iostream.

   List of member functions used as file attributes for the various
   kinds of file opening operation:

   Name of member function    Meaning

   ios::in open a file for reading
   ios::out                       open a file for writing
   ios::app append at the end of a file
   ios::ate seek to the end of a file upon
                                   opening instead of beginning.
   ios::trunc                       delete a file if it exists and
                                   recreate it
   ios::nocreate open a file if a file does not exist
   ios::replace open a file if a file does exist
   ios::binary                       open a file for binary mode;default
                                   is text.
