Hello, I'm writing a C++ program that scans emails for words on our school
"banned word list".

I have got to the point where we can paste text from an email into command
line which gets saved in a .txt file called 'emailscan' - this is then read
by ifstream and scanned for the chosen word which if found is returned with
its location

The problem is that we cannot paste more than a single paragraph of text.

For example if we copy an entire email, which more often than not contains
several carriage returns, only the first block of text before the first
carriage return is fed into the emailscan.txt file and subsequently only this
part of the email is scanned.

Is there a way of ignoring/discarding carriage returns or converting text
after the cin >> operator in order to merge all the text into one 'paragraph'?

Why don't you post your code? The answer depends on how you are doing the
reading.
