請各路英雄好漢來幫忙!!!!!!

[wangcftxz]

請哪位高手指點一下，爲什麽我的二進制保存的dat文件里沒有內容，用寫字板打開成這樣：
编号：？姓名：？體重：？
還有，怎樣將我存好的文本文件和二進制文件再用TSream流打開，我剛學C++，菜鳥，請各路英雄好漢來幫忙!!!!!!

你用二进制写入,用写字板打开当然有乱码

[Q446512799]

能保存然后能正常读取就可以啦0_0

写个代码这么长的还不会对齐，看着真累。代码没问题，能够正确写入数据到txt和bat文件。二进制文件必须用二进制方式来读取。

  binfile.write(p->mc_address,50*sizeof(char));

  end->Next=p;
  p=(struct Employe *)malloc(LEN);
  }while(1);
  system("pause");

只要把这一行改一下就可以读了
binfile.open(mc_binname,ios::binary|ios::out|ios::trunc);//out改为in，然后来读文件
