1. For binary tree, node structure will be
struct node
{
int data;
struct node *left;
struct node *right;
}

2. But our special tree is not Binary Tree .

3. A is a tree root node and it can have ZERO to INFINITY childrens.

Let us assume B, C, D, E,F,G are childrens of A.

4. Now B can have any number childrens . similarly Other children nodes also.

5. diagram representation of tree

A
              / / / | \ \ \
              B C D E F G  H
            //|
            X Y Z ...

4. My answer

struct node 
{
     int data;
     struct node *child;
     struct node *sibling;
};

6. Traversal code 

void PreOrderTraversal( struct node * root )
{
     if( root == NULL )
     {
          return NULL;
     }
     else
     {
           printf("  %d \t", root->data );
           PreOrderTraversal(root->child);
           PreOrderTraversal(root->sibling);
    
     }
}

No, its DFS. Only when the child gets over, the Sibling Node is visited.
