Check Whether Stack is Full or Not ? : Data Structure

We are using Empty Function for Checking whether stack is full or not -

1. Function returns “True” if Stack is Full
2. Function returns “False” if Stack is Not Full.
3. Function Takes “Pointer to Stack”

int full (stack *s)
Return Type : Integer. [If full Stack Return 1 , not full Stack Return 0 ]
Parameter :  Address of Variable of Type Stack .
How to Call this Function From Main ?
typedef struct stack
{
  int data[MAX];
  int top;
}stack;

void main()
{
stack s; // Step 1 : Declare Variable of Type Stack
-------
-------
-------  
-------
-------
-------  
i = full(&s);   // Pass By Reference
------
------
}
Pass “Stack” Variable to “full Function”  using pass by reference.
As full Function returns integer , we have facility to store returned value into some integer variable so we have written [ i = full(&s) ]
Full Function :
int full(stack *s)
{
  if(s->top == MAX-1) //Stack is Full
     return(1);
  else
     return(0);
}
