Program Plan Intro

Elimination of Duplicate Names

Program Plan:

• Include required header file.
• Include required “std” namespace.
• Define main function
  • Declare variable for input file.
  • Declare a variable “ns” in “set” template class of “string” type.
  • Open the given input file.
  • If the input file is fail, then the program terminates.
  • Otherwise, performs “while” loop. This loop executes until the end of file.
    • Declare a variable “name” in “string” type.
    • Read the name from given input file.
    • Then insert a name into “set” template class. If any duplicate name contains, then it remove that name.
  • Close the file.
  • Display statement.
  • Declare a variable “np” in constant iterator of “set” template class.
  • Display the names to generate the invitation list after removing duplicates names using “for” loop.
