The Assignment Assume you're trying to build an e-mailing list by analyzing some random text data pulled from the internet for your unethical Email Spam Business. Your task is to write a C++ program that asks the user to enter a file for processing. You should then test each "word" in the file to determine if the "word" is an email address. The program then outputs, to a separate file called results.out, one per line, every "real" e-mail address contained inside the file as it runs across them. For this assignment, our "words" are white space delimited strings within the file, and if a "word" has an embedded commercial at sign (@) inside it, we shall consider it a possible e-mail address. All possible email addresses will need to be further processed to determine "real" email addresses contained in the data file. To determine if it a "real" email address and worthy of your company's spam mailing list, you will need to process the emails a little further. . First, you should trim any trailing commas (). Thus, the string "BillyBob@mtsu.edu," must appear in the output file as "BillyBob@mtsu.edu" with the trailing comma removed. Only commas at the end of a string are considered trailing; • do not remove non-trailing commas. • Also, some email addresses may contain angle brackets (aka chevrons ) surrounding them. These should be removed; thus, the string "GhostDiet@BooLean.bit," would become "Ghost Diet@BooLean.bit" with the angle brackets removed. ● Finally, double check that a period (.) appears in the email address after the @ symbol. It does not matter where/how many, just that a period exists after the @symbol in a word. • Aside from these three bits of processing, do not worry about any other punctuation; only remove trailing commas, the preceding angle bracket <, the closing angle bracket >, and check for the presence of a period in the second half of the email. These processed email addresses will be our "real" emails.

9: > Console X PI it file p .){ ); se(); History Shell * Instructions x + matter where/how many, just that a period exists after the @symbol in a word. . Aside from these three bits of processing, do not worry about any other punctuation; only remove trailing commas, the preceding angle bracket <, the closing angle bracket >, and check for the presence of a period in the second half of the email. These processed email addresses will be our "real" emails. Program Requirements and Implementation Notes 4 No word will contain more than one @symbol in the file. • Do NOT remove <> that may appear in the middle of words . Do not remove any comma's in the middle of words (only remove the trailing ones) • Ask the user to enter the filename for input. • Write all resulting email output so a separate file called results.out You will need to create your own data files to test your program and make sure it works. Try using a list of fake emails that fit the rules described in the background. Helpful Hints • You may find some of the <cctype> character testing functions and string member functions found in Chapter 10 of the Textbook. Tables 10-1 (section 10.1), 10-2 (section 10.2), and 10-9 (section 10.7) of the textbook useful in programming the solution to this problem. These are also on the course calendar in the Chapter 10 slides. • In particular, the .find(str, pos) and .substr(start, len) member functions of the string class from section 10.7 (table 10-9) might be helpful. . Don't forget to close the files when you are done with them.
