Reading a structure

[sajiv77]

Please see this file .I shall tell the problem.
Compile it if on Linux with
g++ FileName.cpp


include <stdio.h>
#define WRD 2
typedef unsigned char byte;
typedef struct
{
byte hr;
byte trans_no[WRD];
} ABC;

main()
{
ABC ab;
ab.hr=10;
*(int *)ab.trans_no=20;

FILE *fp;
fp = fopen(&quot;testfile&quot;,&quot;w&quot;
fwrite(&ab,sizeof(ABC),1,fp);
fclose(fp);

FILE *fp1;
fp1 = fopen(&quot;testfile&quot;,&quot;r&quot;
fread(&ab,sizeof(ABC),1,fp1);
printf(&quot;Hour is %u \n&quot;,ab.hr);
printf(&quot;Number is %d \n&quot;,ab.trans_no);
fclose(fp1);
}

How do i get the correct value for the trans_no.
Also how do i assign values for the array type variable
