C程序设计语言第一章  “单词计数”统计输入的行数，单词数与字符数
代码如下

#include <stdio.h>

#define IN  1
#define OUT 0

main ()
{
    int c ,n1,nw,nc,state;
    
    state = OUT;
    n1 = nw =nc =0;
    while ((c= getchar ())!=EOF){
        ++nc;
        if(c== ' '||c=='\n'||c=='\t')
            state =OUT;
        else if (state == OUT){
            state = IN;
            ++nw;
        }
    }
    printf ("%d %d %d \n",n1,nw,nc);
}

然后我运行时随便打入几个字母，按回车什么都没有
WHY?

回车后按ctrl+z再回车，另外以上程序改为下面的可能更准确，还有没有行统计
#include <stdio.h>

#define IN  1
#define OUT 0

 main ()
 {
     int c ,n1,nw,nc,state;
     
     state = OUT;
     n1 = nw =nc =0;
     while ((c= getchar ())!=EOF){
         
         if(c== ' '||c=='\n'||c=='\t')
             state =OUT;
         else if (state == OUT){
             state = IN;
             ++nw;
             ++nc;
         }
         else
         ++nc;
     }
     printf ("%d %d %d \n",n1,nw,nc);
 }

不是按回车，windows按ctrl+z，linux按ctrl+d

解决了，谢谢
