Question 1  1 points    Save    
  if b is declared as char b[10] which of these statements does not returns the content of the 10th array cell:

  The address of the 100th cell of an array, a, declared as int a [100]; is given by:  
    &a[100];  
   a + 99;  
   *a[100]  
   (*a)[99]  
 


   Question 3  1 points    Save    
  if a is declared as int a [10], p as int * p, and count as int then which of these pieces of code does not print the integers from a:
 
    for (count=0; count<10; count++) printf("%d ",a[count]);  
   for (p=a,count=0; count < 10; count++) printf("%d ",*p++);  
   for (p=a,count=0; count < 10; printf("%d ",*p),count++,p++);

  If head is of type typeCell * where typeCell is defined as:

typedef struct cell {
     int value;
     struc * cell next;

   Question 6  1 points    Save    
  Suppose that p and q are of type typeCell * where typeCell is defined as:

typedef struct cell {
     int value;
     struc * cell next;
} typeCell;

Moreover assume that p points to one of the typeCell structure of a link list, and that q points to a typeCell structure newly allocated.

Which of these pieces of code correctly inserts the structure newly allocated in the linked list:
 
    q->next = p; p = NULL;  
   q = p->next; p->next = q;  
   p->next = q; q->next = p->next;
 
   q->next = p->next; p->next = q;

  If swap is defined as 

swap (char * p, char * q)
{
    char ch;
    ch = *p, *p = *q, *q = ch;
}

and if p and q are defined of type char* then the effect of the call swap (&p,&q)
 
    is to exchange the content of the 2 pointer variables.  
   is to exchange the content of the memory cells pointed to by p and q.  
   is to do nothing (state of program identical after return of call).  
   is irrelevant as this is clearly incorrect programming.
