Inputting from Textfile, Need to determine if word is on Next line???

[p0gig]

Hey guys, I'm new here as I have a final project coming up and can't figure this out.. it sounds fairly simple

let's say I have a text file that reads

"Hello my name is Bob
I am Testing This Program
Hi there Bob"

I'm just using a simple ifstream loop to read the words as a string

is there anyway at all I can tell so that once my loop hits the word "I" so that I can tell that it's on the 2nd line? or when i hit "Hi", that i'm on the 3rd line?


Just incase this might help, my project is based on a Binary Search Tree, and the program is supposed to read the text file, and after each word is read, i'm supposed to have a pointer that points to an Integer that shows what line its on. So once it reads "Bob" over in the 3rd line.. the node "Bob" will have a pointer that points to "2" and then to "1".

so maybe i'm approaching this wrong?

Thanks for any help!

actually the node "Bob" will have a pointer that points to the int 3 and 1, because those are the lines that have Bob in it.

do i have to resort to using a char? (that would be mighty annoying.......) but even so, i tried a simple loop like

char a;
infile >> a;
if(a==' ')
cout << "SPACEEEEEEE";
if(a=='\n')
cout << "BREAKKKKKKK";

but that's not working either.. it wont detect a space or break...

hopefully i can get a solution that uses strings and not a char

thanks

It's a stream of char, so input stream operator >> does not know any lines.
If you want line numbers, make input loop on line by line basis: use getline() library function, for example:

int lineno;
string line;
for (lineno = 0; getline(cin,line); ++lineno)
{
   // Process the line word by word here...
}

To extract words use istringstream for <sstream>, for example (in loop body):

{
   istringstream ss(line);
   string word;
   while (ss >> word)
   {
      // Process word, use lineno counter...
   }
}
