Traverse Binary Tree using Recursion


Write a C Program to Traverse Binary Tree using Recursion. Here’s simple Program to Traverse Binary Tree using Recursion in C Programming Language.


Recursion : :


  • Recursion is the process of repeating items in a self-similar way. In programming languages, if a program allows you to call a function inside the same function, then it is called a recursive call of the function.
  • The C programming language supports recursion, i.e., a function to call itself. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go into an infinite loop.
  • Recursive functions are very useful to solve many mathematical problems, such as calculating the factorial of a number, generating Fibonacci series, etc.

Problem : :


The following C program, using recursion, performs traversal operation across the nodes in a tree. The tree we have used is the binary search tree. The user generates a tree by inserting integers. The user is also asked to select one of the three modes of traversal, ie, infix, prefix and postfix.

Here is the source code of the C Program to Traverse Binary Tree using Recursion. The C Program is successfully compiled and run on a Linux system. The program output is also shown below.


SOURCE CODE : 



Output : :



Above is the source code for C Program to Traverse Binary Tree using Recursion which is successfully compiled and run on Windows System.The Output of the program is shown above .
