B will be used as a spare pole. The recursive task is to keep moving the disks from one pole to another pole. Let us see how we shall arrive at our base case and the recursive case for our program. As stated initially, our objective is to move all the disks placed on pole A — source pole to pole C — destination pole. Thus, our cases have been derived and they are as given below: a. Recursive Case:.

What is the Tower of Hanoi? In the program source code, hanoifun is the recursive function with four arguments, namely — n , fr , tr and ar. In this C program for Tower of Hanoi, the objective of defining n is to store numbers of discs, and the other character variables fr , tr and ar stand for from rod, to rod and auxiliary rod, respectively.

There is nothing to be provided as input in this program. Copy the source code in Code::Blocks and run it. Alternative C source code for Tower of Hanoi puzzle is given below. It is almost similar to the above one, except that in this code, you can input the number of discs.
