Suppose you have a file named "Countries.txt"
containing a list of countries:
USA, Brazil, Germany, India, Japan, Australia,
Canada, Mexico, China, France,
South Korea, Italy, Spain, Argentina, Russia, Sweden,
Turkey, Nigeria, Egypt, South Africa
Write a C++ program that reads the countries from
the file and performs the following tasks:
Output all the countries in your STL list of strings.
Output all countries that have a length greater than
5 characters.
Output all countries that do not start with the letter
'S'.
Calculate the sum of ASCII values of all characters in
each country and store the result in a histogram of
length 5, where each element represents a range of
values (e.g., 0-100, 101-200, etc.).
Store all the countries in an STL set<string>
container.
Output all unique countries from the set.
Output the total number of entries in your set.
