小弟想将一篇英语文章放到txt文本里，
然后利用文本复制到文本中的过程，统计单词数
程序如下：
#include<stdio.h>
#include<string.h>

void main()
{
  FILE *in, *out;
  char infile[20],outfile[20],ch,string[100],c;
  int num = 0, word = 0, i = 0;
  
  printf("Enter the infile name:\n");
  scanf("%s",infile);
  printf("%s\n",infile);
  printf("Enter the outfile name:\n");
  scanf("%s",outfile);
  printf("%s\n",outfile);
  if ((in = fopen(infile,"rb"))==NULL)
  {
    printf("cannot open infile\n");
    exit(-1);
  }
  if ((out=fopen(outfile,"wb"))==NULL)
  {
    printf("cannot open outfile\n");
    exit(0);
  }
  for(i = 0; !feof(in); i++)
  {
     ch = fgetc(in);
     printf("%c",ch);
     fputc(ch,out);
     string = ch;
     printf("%c\n",string);
  }
  for (i = 0;(c = string) != '\0'; i++)
  {
    if( ch == ' ' && ch == '\n' )
      word = 0;
   else if(word == 0)
    {
      word = 1;
      num++;
    }
  }
   printf("There are %d words in the %s\n",num,infile);
   fclose(in);
   fclose(out);  
}
但输入的结果是：
Enter the infile name：
C\1.txt
C\1.txt
Enter the outfile name:
C\2.txt
C\2.txt
ii

aa
mm

aa

cc
hh
ii
nn
ee
ss
ee
!!

There are 1 words in the 1.txt
其中用了几个printf来检查程序
发现编译器好像不经过：
for (i = 0;(c = string) != '\0'; i++)
  {
    if( ch == ' ' && ch == '\n' )
      word = 0;
   else if(word == 0)
    {
      word = 1;
      num++;
    }
  }
为什么呢？？
向各位高手请教了！
要怎样修改才行？

请问高手在哪？？？

if( ch == ' ' && ch == '\n' )

string = ch;
应该改为string = ch;
以上都不变！

请问有什么区别？

#include<stdio.h>
#include<string.h>

void main()
{
  FILE *in, *out;
  char infile[20],outfile[20],ch,string[100],c;
  int num = 0, word = 0, i = 0;
  
  printf("Enter the infile name:\n");
  scanf("%s",infile);
  printf("%s\n",infile);
  printf("Enter the outfile name:\n");
  scanf("%s",outfile);
  printf("%s\n",outfile);
  if ((in = fopen(infile,"rb"))==NULL)
  {
    printf("cannot open infile\n");
    exit(-1);
  }
  if ((out=fopen(outfile,"wb"))==NULL)
  {
    printf("cannot open outfile\n");
    exit(0);
  }
  for(i = 0; !feof(in); i++)
  {
     ch = fgetc(in);
     printf("%c",ch);
     fputc(ch,out);
     string[i] = ch;
     printf("%c\n",string);
  }
  for (i = 0;(c = string) != '\0'; i++)
  {
    if( ch == ' ' && ch == '\n' )
      word = 0;
   else if(word == 0)
    {
      word = 1;
      num++;
    }
  }
   printf("There are %d words in the %s\n",num,infile);
   fclose(in);
   fclose(out);  
}

急啊！

wc -w yourfile

晕!你的这一段c和ch是何关系? i++了c 和ch 还在原地踏步呢!
for (i = 0;(c = string) != '\0'; i++)
  {
    if( ch == ' ' && ch == '\n' )
      word = 0;
   else if(word == 0)
    {
      word = 1;
      num++;
    }
  }

提醒楼主，标点符号的问题，连续空格的问题，换行断词的问题。
