Write a program that opens a specified text file then displays a list of all the unique words found in the file. Hint: Store each word as an element of a set. 5. Word Frequency Write a program that reads the contents of a text file. The program should create a dictio- nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word "the" appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The

Create an application to keep track of a list of students and their grades in a data structures course using a binary search tree.• Create a class called student that contains 2 data members: name and grade and then create a binary search tree of objects of this class. Make sure you validate the grade (A through F, and ? for in-progress grades).• Create a menu that has the following options:o Add a student -- add the student if he/she is not already in the classo Remove a student -- display “Not Found” error message if the student is not in the class.o Update the grade -- display “Not Found” error message if the student is not in the class.o Display class roster The program should use the binary tree definition. Please list all main, cpp, and hpp files. There must be a Student class, with Student.hpp and Student.cpp files. Do not use structures.

C++ Visual Studio 2019 Write a program that opens a specified text file then displays a list of all the unique words found in the file. Addition to the text book specifications, print the total of unique words in the file. Hint: Store each word as an element of a set. Note: Save text below as the file to use and name it forChap12.txt file for this assignment. Text: No one is unaware of the name of that famous English shipowner, Cunard. In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric tons. Eight years later, the company's assets were increased by four 650-horsepower ships at 1,820 metric tons, and in two more years, by two other vessels of still greater power and tonnage. In 1853 the Cunard Co., whose mail-carrying charter had just been renewed, successively added to its assets the Arabia, the Persia, the China, the Scotia, the Java, and the Russia,…
