i want to add code for implementing stack using linked list (double pointer)

#include <stdio.h>
#include<stdlib.h>
struct node
{
struct node next;
int data;
};
void push(struct node*);
void pop(struct node**);
void display(struct node*);
void peek(struct node*);
int main()
{
struct node *top = 0;
int choice;
printf("Enter 1 to Push\nEnter 2 for Pop\nEnter 3 for Display\nEnter 4 for Peek\nEnter 5 for Exit\n");
do
{
printf("\nEnter you choice: ");
scanf("%d", &choice);
switch (choice)
{
case 1:
push(&top);
break;

    case 2:
        if (top == 0)
        {
            printf("Stack is Empty");
            break;
        }
        else
        {
            pop(&top);
            break;
        }

    case 3: if(top==0)
    {
        printf("Stack is Empty");
        break;
    }
    else
    {
        display(top);
        break;
    }

    case 4: if(top==0)
    {
        printf("Stack is Empty");
        break;
    }
    else
    {
        peek(top);
    }

    case 5: break;

    default: printf("Invalid Choice");
    }
}while(choice!=5);

}
void push(struct node top)
{
struct node newnode;
newnode=(struct node)malloc(sizeof(struct node));
printf("Enter the data: ");
scanf("%d",&newnode->data);
newnode->next=(*top);
(*top)=newnode;

}
void pop(struct node **top)
{
printf("The popped element is %d",(*top)->data);
struct node *temp=(*top);
(*top)=(*top)->next;
free(temp);
}

void display(struct node* top)
{
struct node temp=top;
printf("The elements in the stack are: ");
while(temp!=0)
{
printf("%d ",temp->data);
temp=temp->next;
}
}
void peek(struct node top)
{
printf("The topmost element is %d",top->data);
}
