Everybody sit down in a circle. Ok. Listen to me carefully.

' Woooooo, you scwewy wabbit! '

Now, could someone tell me how many words I just said?

Input and Output

Input to your program would consist of a series of lines, each line containing multiple-words (at least one). A ' word ' is defined as a consecutive sequence of letters (upper and/or lower case).

Your program should output a word count for each line of input. Each word count should is printed on a separate line.

Sample Input

Meep meep!
I tot I taw a putty tat.
I did! I did! I did taw a putty tat.
Shsssssssssh ... I am Hunting wabbits. Heh Heh Heh Heh ...

Sample Output

2
7
9

As long as two words are separated by non-alphanumeric characters, even two words.

Complete code:

#include <cstdio>
#include <cstring>
#include <cctype>
  
char str[300];
  
int main (void)
{
    int i, CNT;
    BOOL Hasalpha;
    while (gets (str))
    {
        cnt = 0;
        Hasalpha = false;
        for (i = 0; str[i]; i++)
        {
            if (Isalpha (str[i)) {
                if (!hasalpha)
                {
                    ++cnt;
                    Hasalpha = true;
                }
            }
            else
            {
                if (hasalpha)
                    Hasalpha = false;
            }
        }
        printf ("%d\n", CNT);
    }
    return 0;
}
