39. Theory question about far pointers.
Hint: Far pointers are 4 bytes in size and local pointers are 2 bytes in size. important: i saw in a previous question paper of accenture which is in the chetana database, some lady wrote that size of an integer in C is 2 bytes and for C++ it is 4 bytes. This is absurd.The size of types is entirely dependent on the compiler used.for DOS Turbo C sizeof int is 2 and float is 4 bytes for windows borland C,C++ size of int is 4 bytes for linux gcc, size of int is 2 bytes. All these depends on the Operating system.Please keep this in mind.

40. Now some questions about extern variables.
41. #include<stdio.h>

int i;
for(i=0;i<5;i++)
printf("%c%c%c%c\n",str[i],i[str],*(str+i),*(i+str));
getch();
}
ans.
hhhh
eeee
llll
llll
note that str[i] and i[str] are the same.in the question paper, the original word is "hello".
main()
{
char str[]={"hell"};
int i;
for(i=0;i<5;i++)
printf("%c%c%c%c\n",str[i],i[str],*(str+i),*(i+str));

42. Which of the following is not defined in string.h strtod,memchr,strspn,strchr
ans . strtod.(defined in STDLIB.H) it is used to convert a string to double.

43. Questions on macros with arguments .same pattern given in TEST UR C SKILLS
eg.#define SQUARE(x) x*x
main()
{
.......
y=SQUARE(2+3);
printf("%d",y);
}
ans. when the macro expands we get 2+3*2+3 = 2+6+3 =11.11 is the correct answer not 25.
eg.#define SQUARE(x) x*x
main()
{
.......
y=SQUARE(2+3);
printf("%d",y);
}
ans. when the macro expands we get 2+3*2+3 = 2+6+3 =11.11 is the correct answer not 25.

****************************************************************
Wipro Paper held at I.S.I-CALCUTTA On 02/08/99
There are 20 questions . Each 3 marks. -1 for wrong answer.
1)How many NAND gates are required to implement an OR-gate?
ans 3
2)There is one Karnaugh map. asked to write the Boolean expresion.
ans is xyz'+xy'z+x'yz
3)They have given one D-flip flops circuit and asked to find the
function.
ans is shift Register.
4)There are 16 address lines and the page size is .5Mbytes .Then How many
pages are there in Virtual memory.
ans is 128
5) There are 3 Interupts .the processor takes 5ns to serve the request.
Interupt 11 takes 24.5ns High Priority
12 takes
13 takes 20ns Low Priority
What is the time range to complete the Interupt 13.
ans is 29.5 to 93.5
6) One question on 8085 address lines.
ans : 8 lines bidirection
7) One question on automata .Given the graph and asked to finnd the
regular expression
ans: (aab+ba) (bab)*
10)Another question on automata. a/ba* indicates
Ans:
the strings which contains either one "a" or a " b" followed by zero
or
more "a" s.
11)
One question on LR pass of compiler.
12)
Binary equialent of 10.625
ans:1010.101
13)
In which addressing mode Effective address is computed by adding a
constant to a register.
ans: Indexed mode
14)
Files (sequential)f1 ,f2,f3,f4,f5,f6 are having 100,200,70,40,250,50
Bytes respectively.In which order the access time is minimum if you are
asked to get all the files.
15)
16)
-20) on c language mainly on pointers.
This is the entire paper. The cut off mark is 25. They selected 16 for
Interiew and selected 7.
They are asking O.sys ,Networks, data structures and giving c problems on
pointers(How to reverse a linked list ..etc).
Wish u all the best.
