Question
Chapter 21, Problem 21.27MAD
Program Plan Intro
Program Plan:
- Include header files.
- Start "main()" function.
- Make a string array "spam" containing 30 spam sample keywords.
- Declare "spamscore" and "countword" variables to store count of spam words and total words respectively.
- Accept "emailmsg".
- Use stringstream "s" for breaking words of emailmsg.
- Start while loop where words from stringstream "s" goes into string "word". Condition of executing loop is till we have words in stream "s".
- Increment countword.
- Use for loop for value i=1 to 30 for each word in array "spam".
- If word is same as one of spam keywords increase spamscore.
- end for loop
- end while loop
- Display Total Number of words in a message.
- Display Total Number of spam words in a message.
- Using type casting calculate "spampercent" as "((float)spamscore/(float)countword)*100;".
- If "spampercent> 30" then display "It's a spam message". else display "It's not a spam".
- Return and exit "main()" function.
