Program Plan Intro

Rational Numbers

Program Plan:

Interface file “stringSet.h”:

• Include required header files.
• Define class “StringSet”.
  • Declare default constructor for “StringSet” class.
  • Declare constructor for “StringSet” with two arguments.
  • Declare function for add a string to a set, remove a string from set, clear whole set, determine the number of strings in a set and display set.
  • Declare function for overload operator “+” and “*”.
  • Declare function search the string in a set.
  • Declare vector variables for strings in set.

Implementation file “stringSet.cpp”:

• Include required header files.
• Define default constructor for “StringSet” class.
• Define constructor for “StringSet” class with two arguments.
• Define function “displaySet()”.
  • This function is used to display each strings in a set.
• Define function “clearSet()”.
  • This function is used to clear entire set.
• Define function “findNumberOfStrings()”.
  • This function is used to return the number of strings in a set.
• Define function “findString()”.
  • This function is used to search a string in set.
• Define function “addString()”.
  • This function is used to add a string to set.
• Define function “removeString()”.
  • This function is used to remove a string from set.
• Define function for overload operator “+” and “*”.

Application file “main.cpp”:

• Include required header file.
• Define main function.
  • Initializes three element in “set” array that is for set one.
  • Create an object of “StringSet” class passing arguments “set” and “3”.
  • Display the strings in set one by calling “displaySet” function.
  • Remove a string from set one by calling the function “removeString”.
  • Add a string to set one by calling the function “addString”.
  • After removing and adding, display the string in set one by calling the function “displaySet”.
  • By using “findNumberOfStrings()”, display the size of elements in set one.
  • Then create the string array “s1” and “s3” and then call with “StringSet” class.
  • Display the set two and set three strings by using “displaySet” function.
  • Compute the intersection of set two and set three using overload operator “*” and then store in “StringSet” object “s4” that is for set four.
  • Then compute the union of set one and set four using overload operator “+” and then store in “StringSet” object “s5” that is for set five.
  • Finally clear the set four by using “clearSet()” function.
