编写函数int countw(char *str),统计字符串str中单词的个数.单词之间以空格, 逗号, 句号作分隔,数字也看做单词.单词之间可能不止一个分隔符.如输入:
It's 10:10 o'clock ,I am late.屏幕上输出"There are 6 words." */
int countw(char *str)
{}
main()
{char s[200];
gets(s);
printf("There are %d words.\n",countw(s));
}
It's 10:10 o'clock ,I am late.屏幕上输出"There are 6 words." */
int countw(char *str)
{}
main()
{char s[200];
gets(s);
printf("There are %d words.\n",countw(s));
}
int countw(char *str)
{int flag=0,n=0;
while(*str)
{if(*str==' '||*str==','||str=='.') flag=0;
else if(flag==0)
{flag=1;
n++;}
str++;}
return n;
}
main()
{char s[200];
gets(s);
printf("There are %d words.\n",countw(s));
}
