Write C code to count the number of leaves in a tree

Here is a C program to do the same...

void count_leaf(mynode *root)

{

   if(root!=NULL)

   {

      count_leaf(root->left);

      

      if(root->left == NULL && root->right==NULL)

      { 

        // This is a leaf!

        count++;

      }


      count_leaf(root->right);

   }

}
