Use STL to write a C++ dictionary project

Description Write a program that reads the attached list of words from an input file. Capitalization will not make a word unique. For example, FOR, for, For, and FoR would all be considered the same word. Sort the dictionary in alphabetical order and then print the list of words all in lowercase letters. This will give you the initial dictionary. Then give the user the option of adding, deleting, or checking whether a word is in the dictionary. Checking whether a word is in the dictionary is similar to the spell checker in Microsoft Word. MS Word checks if a word is in its dictionary and flags words that are not.
