Program plan

source.cpp

• Include the required header files to the program.
• Define the main() function,
  • Include the required function prototype to the program
  • Declare the required variables.
  • Create sets to hold each files words.
  • Read the first file name from the user.
  • Read the second file name from the user.
  • Build the sets for two files.
  • Display the unique words in both files using “showUnion()” function.
  • Make a call to the function “showUnion()”.
  • Display only the words that appear in both files using “ShowIntersection()” function.
  • Make a call to the function “ShowIntersection ()”.
  • Display the words that appear in file #1 but not in file #2 using “showDifference()” function.
  • Make a call to the function “showDifference ()”.
  • Display the words that appear in only one file, but not in both the files using “showSymDiff()”.
• Function definition for the “SetFile ()”:
• Declare a variable “in” to hold the input.
• Create an object for “ifstream”.
• Open the file using “open()”.
• Loop till “infile” reaches end of the file
  • Insert the word to the “setWord”.
• Close the file using “close()”.
• Function definition for the “showUnion()” to display the union of words from two sets:
  • Create a vector to hold the union.
  • Get the union of the sets using the “begin()” and “end()”.
  • Remove the unused words using “resize()” function.
  • Display the result.
• Function definition for the “showIntersection ()” to display the intersection of words from two sets:
  • Create a vector to hold the intersection.
  • Get the intersection of the sets using the “begin()” and “end()”.
  • Remove the unused words using “resize()” function.
  • Display the result.
• Function definition for the “showDifference ()” to show the difference of two sets:
  • Create a vector to hold the difference of two sets.
  • Get the union of the sets using the “begin()” and “end()”.
  • Remove the unused words using “resize()” function.
  • Display the result.
• Function definition for the “showSymDiff ()” to show the symmetric difference of two sets:
  • Create a vector to hold the symmetric difference of two sets.
  • Get the union of the sets using the “begin()” and “end()”.
  • Remove the unused words using “resize()” function.
  • Display the result.
