issues with input (removing punctuation) from dictionary program

[jerger]

my program takes users input (words/sentance) and translates it from english to hmong. I have to main variables, but cannot post my entire code.

char In[999];
CString in;

basically the user cin >> In; then later in = In, then computes using the dictionary. is there anyway i can remove ! commas and periods from the input before translating in my dictionary? i keep getting error codes.

if i do this (first idea)

if (strcmp(In, "!") == 0) {
in = "love";} // In[i - 1];}

if you type in !, you get the word love translated (i used love as a test)

if you type in hello! (you get hello = ) then its blank since it doesn't seperate the word from the !... is there any way to compare the last letter of this special type of character since you cannot analyze it like an array. normally i would do In[j] = "!" or something, but its not a normal character/array so it wont let you look at a position and compare the input.

any ideas?

is there a simpler way in removing punctuation from the translation?

simple way to help me: how can i check/compare the last part of the word for lets say an !, and if it is found, replace it with a space?

I would recommend a regex. They find text and parse it much more easily than strtok and strcmp, et al.

Check out the first two returns from the "boost regex" Google search, I think they can help you do what you need. There are also other regex libraries, but I can't think of them off the top of my head, I'm sure other contributors can add them.

I am not sure that I understood your entire post.

However, it may be useful to tell you that CString has a method Replace which will replace all characters found with something else, or just remove them by replacing them with nothing.

Does that sound useful?

If you want to get fancy and use the much more powerful regular expressions, then I have found the class CAtlRegExp to be workable, though the interface is a bit strange.

yeah i think this is over my level lol.

i was thining maybe since In[999] i could find the number for ! , then look for the ! point? using the number map, rather then the character

Well, if you are doing it that way, I'd recommend looking at the cstring.h reference. I think those will help.

Don't give up on Replace. It isn't hard to use.

    CString in = "love!";
    CString in2 = in;
    in2.Replace( "!", "" );
    cout << in << in2 << endl;

hmm... but cstring doesn't = "a word"... it ='s the input from the cin line... before its sent through the dictionary..

anyway to find a ! in that word, then remove the ! if found?

what are the types of ways for removing the last letter in an array, i remeber something like "word.size( )" and check if its there, then remove it... but i bet there is a better way... err im writing the programmer too

I really would use a string to hold what is read in, then strtok() to find the delimiter, and substr() to pull it out.

That really seems to me to be the asiest way to do what you are saying, but I might be missing something. Can you give a little higher-level idea of what you want to do?

i have to talk to the programmer about posting more information since he doesn't want his code taken.. but

i should study c++ more lol

we have char's, which i don't understand how they are stored since i always though char was one spot, not multiple... so it must be a special string as well.

********
i had an idea this morning, since the char[999] variable is hard to manipulate... maybe when in = In, i could then manipulate in before in is sent to the function.

what is the part of code to check the last part of a char array (last resort string too), char (is it possible) and in addition string.

what i need cleared up is like using word.size() or something similiar in an if statement that i could then check if the last character of the input to check would match a !, if it does, delete it? or change it to a space.

i was thinking i might need t ouse character maps numbers instead of ! for example
