Suppose you have a file named "Countries.txt" that contains a list of countries. Your task is to write a C++ program that performs the following operations: 1. Read the list of countries from "Countries.txt" and store them in an STL list of strings. 2. Output all the countries in the list. 3. Output all countries whose name starts with a vowel. 4. Output all countries that contain more than 7 characters. 5. Calculate the sum of the ASCII values of all letters in each country's name and store the result in a histogram of length 5. Each element in the histogram represents the count of countries whose sum falls within a specific range. For example, if the ranges are [0-1000), [1000-2000), ..., [4000-5000), then the histogram vector contains 5 values. 6. Take all the countries in "Countries.txt" and store them in an STL set container. 7. Output all unique countries in "Countries.txt". 8. Output the total number of entries in your set. Countries.txt = {United States, Canada, Brazil, Germany, India, China, Mexico, Australia, Japan, South Africa, Russia, France, Italy, Spain, Argentina, Sweden, Nigeria, Turkey, Egypt, Chile}
