    Unhappy sTRING ... BUT WHY IT IS STRANGE....

    Hi all,
    can you all look at this ...
    I need to count the words that I got by the input stream..
    why it doesn't count them.... it count just the first word...
    and the first leters.... so Please tell me why it is strange...
    This is the program:
    #include<iostream.h>
    #include<string>

    int main()
    {
    string str1;
    int j=0;
    int counterwords =1;

    cout<< "Please input your text string... \n";
    cin>> str1;
    string::iterator str1_ptr = str1.begin();
    int i=0;
    while (str1_ptr <= str1.end()){
    i++; // increase one visit... to the loop
    if (*str1_ptr == ' ')
    {
    counterwords++; // how many words we have here
    }
    str1_ptr++;// shift one to the righ.. Read one char.
    }
    cout<< " the number of words that you have is ...";
    cout << counterwords<< endl;
    cout<< " I did vist the loop for ..."<< i<< " times" << endl;

    return 0;
    }

    GOOD LUCK!!!

    the problem is relatively simple to fix...

    instead of using a input stream cin like this:

    cin >> str1;

    this stopes the input as soon as the space is encountered... ' '

    use this....

    getline(cin, str1);

    in this particular case the string will read in untill you hit "enter" and will also read in white spaces, just swap those lines and you should be fine....otherwise if you remain with your original line it will only read ONE WORD......

    good luck

    int counterwords =1;

    cout<< "Please input your text string... \n";

    }
    // if (*str1_ptr != ( ' '|| ',' || ';' || '.' ||'!' || '?' ))
    if (*str1_ptr != ','|| *str1_ptr != ' '|| *str1_ptr != '.' || * str1_ptr != '!'|| str1_ptr != '?')
    {
    j++;// how many charactors that the lines have
    }
    str1_ptr++;
    }// while
    int ave =0;
    j--;// to shift j one because it has 1more char

    ave = j/ counterwords ;// what is the avarage of the words in this line...

    I thought it was cin.getline... oh well, I'm probably wrong.
    I'm reasonably new, there's probably a whole heap of different ways.
