1. Consider the following program:
#include<setjmp.h>
static jmp_buf  buf;
 
main()
{
  volatile  int b;
  b =3;
 
  if(setjmp(buf)!=0) 
  {
    printf("%d ", b); 
    exit(0);
  }
  b=5;
  longjmp(buf , 1);
}
The output for this program is:  
(a) 3
(b) 5
(c) 0
(d) None of the above
2. Consider the following program:
main()
{
   struct node
   {
     int a;
     int b;
     int c;    
   };
   struct node  s= { 3, 5,6 };
   struct node *pt = &s;
   printf("%d" ,  *(int*)pt);
}
The output for this program is:
(a) 3
(b) 5
(c) 6
(d) 7
3. Consider the following code segment:
int  foo ( int x , int  n)
{
  int val;
  val =1;
 
  if (n>0)
  {
    if (n%2 == 1)  val = val *x;
   
    val = val * foo(x*x , n/2);
  }
  return val;
}
What function of x and n is compute by this code segment?   
(a) x^n
(b) x*n
(c) n^x
(d) None of the above
4. Consider the following program:
main()
{
  int  a[5] = {1,2,3,4,5};
&nbs
