Question

I have this simple code:

string isNewline(string text)
{   
    string toReturn;
    text == "\r\n" ? toReturn = "(newline)" : toReturn = text;
    return toReturn;
}

this function never returns a “(newline)” string, so I’m guessing that my comparison with newline character is wrong. How can I correct this?

PS. Windows function

There is nothing wrong with your isNewline function.

The problem is how you get the string to be passed to isNewline function.

I suspect you use something like getline(fin,aLine) to get the string like below?

while(getline(fin,aLine)){
   cout<<aLine<<endl; //aLine will never contain newline character because getline never save it
   cout<<isNewline(aLine)<<endl; // so this will never output "(newline)"
}

getline does not save the newline character into aLine
