Hi guys,
I know that there might already be a tread about reading from file but this has a certain hurdle to jump...
I have to read in a 1000 word document into something that will make a list of unique words and how many times they appear. Thats not to bad, but the exception and hard part for me is that each word is seperated by 1 or MORE spaces, which is where i have the problem. If it was only one, and only one, space, i would be a normal read in but the fact that the text file could have "This could be a sentence" would through me off. so my question i need help with is how to read in indiviual words and skip white spaces, even if there are 30 white spaces in a row.

P.S
How would i tell when the file ends
Thanks guys

What is the problem? Just use ifstream's >> operator and it will skip all white space (spaces, tags, etc) between words.
>> How would i tell when the file ends
when the loop below exits

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
And use a std::map<std::string, int> to count the occurences of the words in the file:
- if you cannot find the word in the map, then create a new map entry for that word with the int set to 1
- if you fin the word in the map, increment the int by 1
- if you cannot find the word in the map, then create a new map entry for that word with the int set to 1
- if you fin the word in the map, increment the int by 1
If you are forced to reinvent the wheel at least try to invent a better one!
