please tell me where in this corrected code I made mistake:>

why this portion of code:> 



if(c==0x0D)
        then
        {
            //fprintf(stream2,"%s", "\\r\\n");
//            if(c==EOF)
//            then 
//                printf("A");
//            else
//                printf("%s",c);
            printf("%s", c);
        }
//        else
//            word_number++;
