C Program to implement Ackermann function 

Write a C Program to implement Ackermann function using recursion. Here’s simple Program to implement Ackermann’s function 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.

Ackermann Function

The Ackermann function is the simplest example of a well-defined total function which is computable but not primitive recursive, providing a counterexample to the belief in the early 1900’s that every computable function was also primitive recursive . It grows faster than an exponential function, or even a multiple exponential function.

Below is the source code for C Program to implement Ackermann function using recursion which is successfully compiled and run on Windows System to produce desired output as shown below :
