Given method checks for #define MAX 10 typedef struct stack { int top; int item [MAX]; }stack; int function(stack *s) { if(s->top return 1; else return 0 ; } *

A. invalid index

B. infinite stack

C. full stack

D. empty stack

Sol3:

The given method function checks for an empty stack.

In the typedef statement, a stack is defined as a structure containing an integer top and an array of integers item with a maximum size of 10.

The function takes a pointer to a stack as an argument and returns 1 if the top element of the stack is -1, indicating an empty stack. Otherwise, it returns 0, indicating a non-empty stack.

Therefore, the correct answer is \"empty stack\".
