Add the following recursive method to your binary tree's node class:
size_t Node::count_leaves()
{
if (!left && !right) return 1; // this node is a leaf
size_t count = 0;
if (left) count += left-count_leaves(); // count leaves on left
if (right) count += right-leaves(); // count leaves on right;
return count; // return total leaves.
}
To count the leaves of the entire tree, call the method on the root node of the tree. To count the leaves of a subtree, call the method on the root node of the subtree.

How many leaf nodes does the full binary tree of height h 3 have?
For a full binary tree of height 3 there are 4 leaf nodes. E.g., 1 root, 2 children and 4 grandchildren.
Program for count the total number of node in binary tree?
The number of nodes in any subtree is the number of nodes in its left subtree, plus the number of nodes in its right subtree, plus one, so you can use a recursive algorithm and start at the root.unsigned intbinarytree_count_recursive(const node *root){unsigned int count = 0;if (root != NULL) {count = 1 + binarytree_count_recursive(root->left)+ binarytree_count_recursive(root->right);}return count;}
What are the properties of binary tree?
A binary tree of n elements has n-1 edgesA binary tree of height h has at least h and at most 2h - 1 elementsThe height of a binary tree with n elements is at most n and at least ?log2 (n+1)?
When we insert a new node in a binary search tree will it become an internal node or terminal node?
It will be come a terminal node. Normally we call terminal nodes leaf nodes because a leaf has no branches other than its parent.
Type of binary tree?
A rooted binary tree is a tree with a root node in which every node has at most two children.A full binary tree (sometimes proper binary treeor 2-tree or strictly binary tree) is a tree in which every node other than the leaves has two children. Sometimes a full tree is ambiguously defined as a perfect tree.A perfect binary tree is a full binary tree in which all leaves are at the same depth or same level, and in which every parent has two children.[1] (This is ambiguously also called a complete binary tree.)A complete binary tree is a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible.[2]An infinite complete binary tree is a tree with a countably infinite number of levels, in which every node has two children, so that there are 2d nodes at level d. The set of all nodes is countably infinite, but the set of all infinite paths from the root is uncountable: it has the cardinality of the continuum. These paths corresponding by an order preserving bijection to the points of the Cantor set, or (through the example of the Stern-Brocot tree) to the set of positive irrational numbers.A balanced binary tree is commonly defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1,[3] although in general it is a binary tree where no leaf is much farther away from the root than any other leaf. (Different balancing schemes allow different definitions of "much farther"[4]). Binary trees that are balanced according to this definition have a predictable depth (how many nodes are traversed from the root to a leaf, root counting as node 0 and subsequent as 1, 2, ..., depth). This depth is equal to the integer part of where is the number of nodes on the balanced tree. Example 1: balanced tree with 1 node, (depth = 0). Example 2: balanced tree with 3 nodes, (depth=1). Example 3: balanced tree with 5 nodes, (depth of tree is 2 nodes).A rooted complete binary tree can be identified with a free magma.A degenerate tree is a tree where for each parent node, there is only one associated child node. This means that in a performance measurement, the tree will behave like a linked list data structure.Note that this terminology often varies in the literature, especially with respect to the meaning of "complete" and "full".
What is the Algorithm to count the number of leaf nodes in binary tree?
int countleaves(struct node* root){ if(root!=null) { countleaves(root->left); if(root->left==NULL&&root->right==NULL) { count++; } countleaves(root->right); } }
The height of Complete Binary tree is in terms of :option1. n2. logn3. n^2?
The height of a complete binary tree is in terms of log(n) where n is the number of nodes in the tree. The height of a complete binary tree is the maximum number of edges from the root to a leaf, and in a complete binary tree, the number of leaf nodes is equal to the number of internal nodes plus 1. Since the number of leaf nodes in a complete binary tree is equal to 2^h where h is the height of the tree, we can use log2 to find the height of a complete binary tree in terms of the number of nodes.
What is the number of nodes of degree 2 in binary tree which has n leaf nodes?
Ne=N2+1Here Ne=no. of leaf nodesN2= no. of nodes of degree 2
How do you determine Surface area of leaf without using any instrument?
Here's what you do... take a graph paper.. the 1mm x 1mm graduated. trace the leaf on the graph paper. remove the leaf. then count the whole squares occupied by the leaf. write down the number. count the half 3/4th filled squares and write the number down. count the number of half filled squares and divide the number by two and write it down. leave out 1/4th filled squares. add the numbers you have written down. the number you get is the surface area of one side of leaf. doubling it will give you the surface area of the entire leaf in sq cm
What is the difference between strictly binary tree and complete binary tree?
Complete Binary tree: -All leaf nodes are found at the tree depth level -All nodes(non-leaf) have two children Strictly Binary tree: -Nodes can have 0 or 2 children
What is the difference between extended binary tree and complete binary tree?
Complete Binary tree: All leaf nodes are found at the tree depth level and All non-leaf nodes have two children. Extended Binary tree: Nodes can have either 0 or 2 children.
What is the number of nodes in a strictly binary tree which has n leaves?
IF EVERY NON-LEAF NODE IN A BINARY TREE HAS HAS NONEMPTY LEFT AND RIGHT SUBTREES, THE TREE IS TERMED AS A STRICTLY BINARY TREE. SUCH A TREE WITH n LEAVES ALWAYS CONTAINS 2n-1 NODES.
How many leaf nodes does the full binary tree of height h 3 have?
For a full binary tree of height 3 there are 4 leaf nodes. E.g., 1 root, 2 children and 4 grandchildren.
What do you mean by strictly binary tree?
A strictly binary tree is a tree in which every node other than the leaf nodes has exactly two children. OR in the Graph Theory perspective a tree having it's root vertex with degree 2 and all other non-leaf vertex of degree 3 and leaf vertex of degree 1, is called as the strictly binary tree. it is also called as the 2-tree or full binary tree.
Program for count the total number of node in binary tree?
The number of nodes in any subtree is the number of nodes in its left subtree, plus the number of nodes in its right subtree, plus one, so you can use a recursive algorithm and start at the root.unsigned intbinarytree_count_recursive(const node *root){unsigned int count = 0;if (root != NULL) {count = 1 + binarytree_count_recursive(root->left)+ binarytree_count_recursive(root->right);}return count;}
