C++HurdleWords The HurdleWords class is mostly provided to you. HurdleWords is constructed from two files in the data/ folder: ● valid_guesses.txt (all 5 letter guesses considered to be valid words to guess), and ● valid_hurdles.txt (all words that may be selected to be the secret Hurdle.) ● Note: you may edit both text files if you’d like to add custom words to your game. HurdleWords stores all potential valid Hurdles from valid_hurdles.txt into a vector of strings (valid_hurdles_), and all valid guesses from valid_guesses.txt into an unordered set of strings (valid_guesses_). A set is simply a data structure that contains no duplicates and allows for a speedy lookup to check if a given element exists within the set. Because there are over 10,000 valid guesses, we store them in an unordered set to leverage their speediness, as you will need to check if a user-submitted guess is considered valid (i.e. their guess is considered a valid guess in the dictionary). You are responsible for…

For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed). Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock. Read all the food items from the text file “Items.txt” Display all the food items available for this food truck.
