3. Graphics:One more question Ans: may be none of the above

4. How can you call a function written in FORTRAN from a C program ?

5. Normal question on pointer addition

6. A question on 64 bit OS’s and Virtual Memory it will be having

7. Another question on 64 bit OS

8. A structure was given and it contained normal data as well as some bit-wise data.You had to find the total size taken up by the structure

9. A big code with lots of pointers. There was a struct which contained 2 arrays. Then an array of that structure was declared. The code used these structures and you had to find the values of a variable ‘j’ at various points inside the code.

10. A code which had some declarations of some data items. There were a couple of normal data items(char,int..) and some pointers as well and a malloc call. You have to find the total memory taken up in the stack(Hint:Pointers

11. A code which had some declarations of some data items. There were a couple of normal data items(char,int..) and some pointers as well and a malloc call. You have to find the total memory taken up in the stack(Hint:Pointers and all are allocated in heap, not in stack, so dont count them).Also in most of these questions, they were specifying that the OS was 32 bit.

12. A question on nesting of pointers. There was this pointer to a function which returned an array of char pointers…..You had to give the exact definition of the function

13. Value of 2 particular variables in C(MAXINT and some other constant)

14. What do you need to do to open more than 10 files simultaneously in Microsoft Operating System?-change stdio.h/change CONFIG.SYS/compiler dependent
