    extracting words from an array of words

    Hello all, I'm having a lot of trouble with extracting individual words from an array of words. First I input a file into an array, and then I'm trying to extract each word into a seperate cstring, I can do it if the number of words is given, but if not then I'm drawing a blank. But, lets say that I know that maximum number of words is 25, what then?

    this is what I have so far:
    Code:
    #include <iostream>
    #include <fstream>
    using namespace std;
    
    const int SIZE = 81;
    const int MAX_WORDS = 25;
    
    int main()
    {
    
    	ifstream inStream;
    	//ofstream outStream;
    	
    	inStream.open("darwin.txt");
    	if ( inStream.fail() ) {
          cout << "Input file opening for darwin.txt failed.  Exiting...\n\n";
          exit(-1);
        }
     
    	
    	char theWords[MAX_WORDS][SIZE];
    	int wordRow = 0;
    	int count = 0;         
                    int i;
    	int numberOfWords=0;
    	char j; 
    	char *pWord;
    	char word[SIZE/2][SIZE];
    	int c=0;
    	
    	while ( inStream >> theWords[wordRow]) 
    	{
          wordRow++;
        }
        ............and here I'm drawing a blank
    
    	
    	return 0;
    should I test if the an element of theWords array is a blank space " ", but then how could I account for punctuation? I know I don't have much done this time, but any suggestions would be much appreciated,

    thanks

    if your array of chars is null terminated i.e. a c style string then you could use strtok(). many examples on the boards. search button is up and right!
    Free the weed!! Class B to class C is not good enough!!

    Thanks a lot, I did used search before posting but I was using different keywords...it's weird that my book doesn't even include the strtok() in its contexts...this makes things much simpler...I'll keep working on it...thanks a lot,
