Can I use relational operators on struct variables?On struct variables, relational operations can be utilized. A struct variable’s data must be read one member at a time. A function can return an array of values. A struct value can be returned by a function. In the C++ programming language, the dot (.) operator is known as the “Class Member Access Operator” and it is used to access public members of a class. A class’s public members include its data members (variables) and member functions (class methods).
The Subscript variable is used to access array elements, while the dot [.] operator is used to access structure members. Nesting of two structures refers to a structure written inside another structure.

count = count + 1
print("#" + str(count) +": You entered the word " + data)
data = input("Please enter the next word: ")
print("A total of "+ str(count) + " words were entered.")
Explanation:
So the code is asking us to put in words from the user and then it will count those words in total.
so first we want the code to start from 0 to get an accurate count
count = 0
boom, first line.
second you will ask the user to input a word with a data string on it to then have it stored
data = input('Please enter the next word: ')
now if the user enters DONE the code will know to stop and give the total
while data != "DONE":
then we will have the code count the words we inputed,
count = count + 1
next we want to know how many words we put in "the whole point of the code.
print("#" + str(count) +": You entered the word " + data)
the data is very important
if the user didnt enter DONE we want the code to continue so we ask the user to enter another word
data = input("Please enter the next word: ")
now we do the same thing as the code before, now we show how many words were entered in total
print("A total of "+ str(count) + " words were entered.")
