Question

Question 4 (1 point) Consider the following piece of C code. What can be said about the pop() function in this piece of code only? struct node { struct node *next; void *value; }; static struct node *stack; void * pop() { void * value = stack->value;

Answer 1

Answer:

An object life-time exceeds binding lifetime

Code:
struct node
{
   struct node *next;
   void *value;
};

static struct node *stack;

void *pop()
{
void *value=statck->value;
free(stack);  
stack=stack->next;
return value;
}

void push(void *value)
{
   struct node *node=malloc(sizeof(struct node));
   node->value=value;
   node->next=stack;
   stack=node;
}
