13. In a file A…Z characters are written.if we open the file using fopen and

14. Same question with

lseek(fp,10,0);

c=getc(fp);

printf(“%c”,c);

ans. 11th character will be printed “K” verify.

15. Theory question about far pointers.
Hint: Far pointers are 4 bytes in size and local pointers are 2 bytes in size.

ans.

hhhh


eeeel

lllll
