关于判断输入字符的单词个数的非数组做法

以空格为分界单词的元素，空格可多个，空格可在首单词之前。代码先上

#include<stdio.h>int main(){char c;int flag = 0;int counter = 0;while( ( c = getchar() ) != '\n' ){if( c != 32 ){if( flag ){continue;}counter ++;flag = 1;continue;}flag = 0;}printf("%d", counter);return 0;}

注意要点：( c = getchar() ) != '\n'       中c = getchar() 需要用()；
