    Binary trees are data structures that can have at most two children per parent node and are used for search algorithms, 3D games, networking, and cryptography. This document discusses the basics of binary trees, including the different types (full, complete, and perfect), and provides an example C program to implement a simple binary tree with four nodes and integers as data.

    Binary trees are types of data structures that have many uses.

    They can be applied in search, 3D video


    games, high-bandwidth network routers, some peer-to-peer programs and cryptography. In this lesson,
    we'll explore the basics and application of binary trees. We will also implement a binary tree example.

    What Is a Binary Tree?

    A normal tree has no restrictions on the number of children each node can have. Binary trees,
    on the other hand, can have at most two children for each parent. Every node contains a 'left'
    reference, a 'right' reference, and a data element. The topmost node in the tree is called the
    root node. Nodes with children are parent nodes, and the child nodes contain references to
    their parents. A node with no children is called a leaf node. Thus, each node in a binary tree can
    have either 0, 1 or 2 children as shown in Figure 1.

    Types & Implementation

    There are three different types of binary trees that will be discussed in this lesson:

     Full binary tree: Every node other than leaf nodes has 2 child nodes.
     Complete binary tree: All levels are filled except possibly the last one, and all nodes are
    filled in as far left as possible.
     Perfect binary tree: All nodes have two children and all leaves are at the same level.
    We can represent a tree node structure in the C programming language. Consider an example that
    consists of a node with integer data. We can then add to this to create a simple binary tree with four
    nodes:

    1. struct node
    2. {
    3.  int data;
    4.   struct node *left;
    5.   struct node *right;
    6. };
    7. /* newNode() allocates a new node with the given data and NULL left and
    8. right pointers. */
    9.  struct node* newNode(int data)
    10. {
    11. // Allocate memory for new node
    12.  struct node* node = (struct node*)malloc(sizeof(struct node));
    13. // Assign data to this node
    14.   node->data = data;
    15. // Initialize left and right children as NULL
    16.   node->left = NULL;
    17.   node->right = NULL;
    18.  return(node);
    19. }
    20. int main()
    21. {
    22. /*create root*/
    23.  struct node *root = newNode(1);
    24.   root->left = newNode(2);
    25.   root->right = newNode(3);
    26.   root->left->left = newNode(4);
    27.  getchar();
    28. return 0;
    29. }

    The result of the code is:
