problem with string breakline

[snoopy198520]

Do i still need to append? and do i get the string break. i try cannot only the first line break.
how are you?
I am fine. What about you? I fine too!

the txt file is :

How are you? I am fine. What about you? I fine too!

How are you?
I am fine.
what about you?
i fine too!

//find file and word
cin >> file name;
cin >> searchWord; // cin you

the output display:
how are you?
what about you?
how are you?
what about you?

this is my code somewhere go wrong:
while (!fin.eof())
{

getline(fin,line);

for(int i=0; i < line.length(); i++)
line[i] = tolower(line[i]);

for(int i=0; i < wordSearch.length(); i++)
wordSearch[i] = tolower(wordSearch[i]);

line.append(str1, 0, line.length()); // join the sentence to a line

found = line.find(wordSearch); // search for cin words
pos = line.find_first_of(".!?");

if ((found!=string::npos) &&( pos!=string::npos))
{

str3 = line.substr (0,pos+1);
str2 = line.substr(pos+1);

cout <<str3<< '\n' << str2 << endl;

}

}

}

I am fine.
you are good. you.
i fine too!

output result:

Shouldn't be too bad - split the string by '.', '?', and '!'. Then split by ' '. Keep any groups in which 'you' occurs.

line = tolower(line);

for(int i=0; i < wordSearch.length(); i++)
wordSearch = tolower(wordSearch);

line.append(str1); // join the sentence to a line

found = line.find(wordSearch); // search for cin words
pos = line.find_first_of(".!?");

if (found!=string::npos)
{
str3 = line.substr (0, pos);
str2 = line.substr(pos+1);

cout <<str3<< '\n' << str2 << endl;
