错在那里?a和b两个文件内容比较,如果b中有a的内容那么a中相对应的数组标志为1,否则为0.内容如下:
a.txt           b.txt


       1231435     2342424

       3425255     6758582

       3226342     2354255<-

       2542525     7895422

   -> 2354255     9865433  

结果应是ch[ 5 ].Flag =1,其他为0.可结果不对!请大家赐教!

#include<stdio.h>

main()

{

 FILE    *fp;

 FILE   *fpp;

 int record;

 int conum;

 struct ch { char txt[ 7 ]; int Flag; }ch[ 10 ];

 struct ci { char txt[ 7 ]; }ci[ 10 ];



 fp = fopen( "a.txt" , "rb" );

 if( fp == NULL )

 {

  printf( "\na.txt is NULL!!!");

  return( 0 );

 }



 fpp = fopen( "b.txt" , "rb" );

 if( fpp == NULL )

 {

  printf( "\nb.txt is NULL!!!");

  return( 0 );

 }



 printf( "\nRead text!" );

 

 for( record = 0 ; record < 10 ; record ++)

  fscanf( fp , "%7s" , ch[ record ].txt );

  

 for( conum = 0 ; conum < 10 ; conum ++ )

  fscanf( fpp , "%7s" , ci[ conum ].txt );

  

 

 for( record = 0 ; record < 10 ; record ++ )

 {ch[ record ].Flag = 0;

  for( conum = 0 ; conum < 10 ; conum ++ )

    {

    if( strcmp( ch[ record ].txt , ci[ conum ].txt ) != 0 )

      ch[ record ].Flag = 1;



     else

      ch[ record ].Flag = 0;

    }

 }

  for( record = 0 ; record < 10 ; record ++ )

  printf( "\n%d" , ch[ record ].Flag );

}

没有那位高人可以指点一下迷津吗?

应该把else ch[recore].flag=0改为else {ch[recore].flag=0;break;}。

关键错误在这里： struct ch { char txt[ 7 ]; int Flag; }ch[ 10 ]; struct ci { char txt[ 7 ]; }ci[ 10 ]; 数组下标错了 应该是8 其它还有些小错误 正确的如下： #include<stdio.h> main() { FILE *fp,*fpp; int record,conum; struct ch { char txt[ 8 ]; int Flag; }ch[ 10 ]; struct ci { char txt[ 8 ]; }ci[ 10 ];

if((fp = fopen( "a.txt" , "r" ))== NULL ) {printf( "\na.txt is NULL!!!"); return( 0 );} if((fpp = fopen( "b.txt" ,"r" ))== NULL ) {printf( "\nb.txt is NULL!!!"); return( 0 );} for( record = 0 ; record < 10 ; record ++) {fscanf( fpp,"%s",ci[record].txt); fscanf( fp,"%s",ch[record].txt);} for( record = 0 ; *ch[record].txt; record ++ ) {ch[ record ].Flag = 0; for( conum = 0 ; *ci[conum].txt; conum ++ ) if( !strcmp( ch[ record ].txt , ci[ conum ].txt ) ) {ch[ record ].Flag = 1;break;} } for( record = 0 ; *ch[record].txt ; record ++ ) printf( "\n%d" , ch[ record ].Flag );

}
