There was a Technical Interview,followed by personal interview.
Mainly concetrating on the interesting subjects.


write a C code
1.to reverse a string using a recursive function, without
swapping or using an extra memory.
2.To reverse a linked list as above.

given a macro like
#define MAX(A,B) {to return that is larger}
what will MAX(i++,j),MAX(i,j++) return.

Difference between Macro and ordinary definition.
Difference between Class and Struct.

Testing and Maintenance.(will you work in it and what are they)

Give the outputs of a compiler and assembler and loader
and linker etc.
If a new data structure, suppose a queue is to be added

C TEST

1. main()
{
int arr[100];
int c:
int N;
for(i=-:i<N;i++)
arr=i;
minvalue i = .....
Maxvalue i = ..... Ans 0,100 resp

2. Union Problem ..... Ans : a or c

3. for n=2 the following fn returning value is
int fun(int n)
{
for(i = 1;i<=n;i++)
for(j=i;j<=i;j++)
sum=sum+j;
return(sum);
} Ans 6

4. Calculate sum=1+1+2+1+2+3+1......
Ans i<=x;j<=i

5. for x=2 y=3 z=1
the following fn return
int fun(int n; int y; int z)
{
int sum
for(i=x;i<=y;i++)
for(j=1;j<=z;z++)
sum=sum+z;
return sum
}
Ans 0(check)

6. The values of sum from above fn
for x=0; y=0;z=1 Ans 1
7.how can you insert the following values in stack and numbers
10,20,30,40,50.60
stack [][][][][][]
numb [][][][][][][]

Ans
60 50 40 30 20 10
10 20 30 40 50 60
check.

8. # if ndif XYZ

#include "XYZ.h"
#endif
what is meaning ?
Ans:
if XYZ is not defined then only include the header file XYZ.h.

9. p:malloc(int*sizeof(int));

ans: a

10.a=5 b=10 c=7
(a c)?a:((b c)?b:c) ans 10
11. debugging eliminates Ans[c]
ans: both logical & ruin time errors.
12. int term (int x)
{ int sum=0;int i;
for(i=0;i<=5;i++)
sum+=x; /*problel is wrong but Ans is 650.*/
return(sum);
} Ans 650
the above fn value for x=150
13.int x;
scanf("%d",x);
-------------
--------------
what is error in the above program

14.int a[] = { 1, , 9,2.......}
int *p;
p=&a[2];
printf("%s",p);
a)7 b)2 c)4407 d)none

ans: d
15.a[][] = {1,2},{3,4}
b[] [] ={
void fun(A,B)
int i,j;
for(i=1;i<N;i++)
for(j=1;j<N;j++)
sum=sum+A[j];
return sum;
}
what is wrong in the above function?

3. char *(*(*a(N))())();?
4.*p++ = ?
5 int i=7
printf( "%d \n",i++ i++) o/p =? ans 56
6.n=2 pow((2.0,n),++n)?
7 #define macro for ( i,g) ?
8. int reg=2 is there any wrong ? write a reason
