fwrite(&arr,sizeof(int),1,fp);
sizeof(int)表示你写入的一块的大小，你用的是一个int大小。
1表示你要写入的块的数目。
显然在你机器上一个int是4个字节，而arr的类型是char *，一个char是1个字节，所以你写入4个字节大小的数据时就会写入四个字符。
如果你要写入全部字符，改成
fwrite(&arr,sizeof(char),10,fp);
fwrite(&arr,sizeof(int),1,fp);
第二个参数sizeof(int)为4, 也就是说只能写入四个字节,
这里应该改成数组的大小
fwrite(arr,strlen(arr),1,fp);
arr作为参数是一个指针, 不用再加取地址符&
这样就可以了.
其实你写入的是二进制, 因为你写如的都是ascii码, 都占用一个字符, 所以看起来和文本数据一样, 如果你输入一个汉字就看出来了
fwrite(&arr,sizeof(int),1,fp);
应该改成：
fwrite(&arr,strlen(arr),1,fp);
而且还需要在头文件中加入
#include "string.h"就可以了
楼上的很对！
