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 will 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 be printed on a separate line.

Sample Input

KEY：统计单词数目，用isalpha（）判断字符是否为字母，每当当前字符为字母而后面一个字符不是字母的时候，意味着一个单词的结束，计数器+1

#include <iostream>#include <ctype.h>using namespace std;int main(){   char text[1000];   while(fgets(text,sizeof(text),stdin))   {    int i = 0,count = 0;    while(text[i] != '\0' )    {                  if(isalpha(text[i]) && !isalpha(text[i+1]))          count++ ;      i++;                          }    cout<< count <<endl;   }                 return 0;}
