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;
