cstring question

[jin]

Hey i am tryin to read in a file and store the letters in a 2Ds ctstring. So that words[word number][number of letters]. In java i would have used a string tokenizer to determine when a word finishes and the next starts. Any help is appreciated.

thnx.

You could use std::strings instead of character strings. And use std::vector instead of an array, it automatically manages it's size.

Unless of course this question is limited to C.

thnx for the reply but i havent yet learned about std::string and std::vector. i think i might have gotten it.

code:

int y = 0;        int x = 0;        char letter;        while (! inFile.eof())       {               inFile.get (letter);               if (!isspace(letter))               {                words [x] [y] = letter;                y++;                }                else                {                y=0;                x++;                }      }

This is what i have so far and it works if there is one space between characters but if there is more. it saves the space in the variable. Any thoughts.

thnx

File contents are:
abc <space> def <space><space>ghi <enter>

the output i get is:
abc
def
<empty line>
ghi

the output i need is:
abc
def
ghi

thnx.

First off, let's try formatting this code nicely.

code:

int y = 0; int x = 0; char letter; while (!inFile.eof()) {    inFile.get(letter);    if (!isspace(letter))    {       words[x][y] = letter;       y++;    }    else    {       y = 0;       x++;    } }

Now, let's step through what happens on input of:

code:

abc def  ghi

code:

x = 0 y = 0 letter = 'a' 'a' is not a space words[0][0] = 'a' y = 1 x = 0 y = 1 letter = 'b' 'a' is not a space words[0][1] = 'b' y = 2 x = 0 y = 2 letter = 'c' 'c' is not a space words[0][2] = 'c' y = 3 x = 0 y = 3 letter = ' ' ' ' is a space y = 0 x = 1 x = 1 y = 0 letter = 'd' 'd' is not a space words[1][0] = 'd' y = 1 x = 1 y = 1 letter = 'e' 'e' is not a space words[1][1] = 'e' y = 2 x = 1 y = 2 letter = 'f' 'f' is not a space words[1][2] = 'f' y = 3 x = 1 y = 3 letter = ' ' ' ' is a space y = 0 x = 2 x = 2 y = 0 letter = ' ' ' ' is a space y = 0 x = 3 x = 3 y = 0 letter = 'g' 'g' is not a space words[3][0] = 'g' y = 1 x = 3 y = 1 letter = 'h' 'h' is not a space words[3][1] = 'h' y = 2 x = 3 y = 2 letter = 'i' 'i' is not a space words[3][2] = 'i' y = 3

Now, do you see where the error is occurring?

@jin:

if using C++, look into iostream too;

if using C, look into scanf (careful what you do with it though).

In your current program:
To get rid of the extra spaces, simply read away all spaces before a word.
(A loop will do). ungetc() can help.

thnx for all your help i got it working now.
