I need to write a program that reads a text file, which contains words that are followed with a preposition. If the preposition is wrong for the word, the program is supposed to warn the reader and suggest the correct preposition that follows a specific word.
Ex:
>> The decrease *of* (in) diseases is a positive development...
the preposition of is not correct, in is.
I am having a hard time starting, I don't know how the whole structure should look? maybe a dicitionary with the words (as keys) and prepositon. {"decrease":"of "} ?
Could anybody help =)??

A dictionary sounds like a good idea to me. You'll also probably want a list of all the prepositions you might encounter so your program knows where to check for the proper prepositions. Id suggest reading in the whole text file as a string, and then using "split(' ')" to break the string into a list that you can look through word by word. That way when you come across a preposition, you can back up one index and check the word in front of it.
Maybe something like this: - prepositions = [] #put all your prepositions in here
-
words = {} #put {word : preposition} pairs in here
-
file = open("file.txt", "r")
-
text = file.read()
-
text = text.split(' ')
-
for i in range(len(text)):
-
if text[i] in prepositions and i > 0:
-
#make sure that text[i - 1] is the right word
-
#then suggest the right preposition if needed
Remember that your also going to have to ignore punctuation some how.

Hello all,
I've put together a small program to count the number of characters and
'words' in a text file. The minimum length of a word, (in terms of no.
of characters), as well as word delimiting characters can be specified
on the command line. The default delimiting characters built into the
program are space, newline, tab, carriage return, form feed, vertical
tab, comma and null. If a 'u' or 'U' is specified as the last command

SUBJECT: How to make this program more efficient?
In my program, a thread will check update from server periodically and
generate a stl::map for other part of this program to read data from.
Let's name the update method as doUpdate and stl::map read methods as
getData and copyData.
Since stl::map is not thread-safe, we should do synchronization by
ourselves. A usable solution is to create a boost::mutex::scoped_lock

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

For most users, this new feature is actually very convenient. If you want to control the update process,...
