2.the function strcmp(str1,str2) returns

3. int *x[](); means

4.#define PRINT(int) printf("int=%d",int);
main()
{
int x,y,z;
x=03;y=-1;z=01;
PRINT(x^x);
z<<=3;PRINT(x); y>>=3;PRINT(y);
}

o/p =?
12.o/p=?
int i;
i=1;
i=i+2*i++;
printf(%d,i);

8.{ ch='A';

c 3 2
d. error

11.#include

}
o/p=?

13. int sum(n)
int n;
if(n<1)return>(y)?(x):(y)
{ int i=10;j=5;k=0;
k= MAN(i++,++j)
printf(%d %d %d %d,i,j,k)
}

16) a=10;b=5; c=3;d=3;
if(a < c="d++)">
show(int t,va_list ptr1)
{
int a,x,i;
a=va_arg(ptr1,int)
printf("\n %d",a)
}
display(char)
{int x;
listptr;
va_star(otr,s);
n=va_arg(ptr,int);
show(x,ptr);
}
main()
{

a)myprog jan,feb,mar,apr
b)rev
c)jan,feb,mar,apr
d)error
.......................

18.what is o/p

while(i--)
{
int i=100
i--;
printf("%d..",i);
}
}
a) infinite loop
b) error
c) 99..99..99..99
d) 3..22..1..
..........................

20)what is the o/p of the program
main()
{
int rows=3,colums=4;
int a[rows][colums]={1,2,3,4,5,6,7,8,9,10,11,12};
i=j=k=99;
for(i=0;i < j="0;j" k="a[i][j];" style="font-weight: bold;">Interview:

In the interview they will ask you puzzles and technical questions from any language you tell them.For puzzles refer book told in evalueserve placement paper in this blog.

If you tell you know C,they will ask you questions from c only.But its better is you have knowledge of c++.

Electronics guys should have knowledge of unix and java for clearing the test only.

Some of the puzzles which I remember are:
1.Spider Puzzle
2.Counting number of monkeys
3.8 dots puzzle
4.Measuring time by candles and rope

More Puzzles asked are discussed in logical puzzle and brain exercise section.

So Work hard and get your dream company.

Best of luck...................................
