C Program to implement Binary Search


Write a C Program to implement Binary Search using Recursion.¬†Here’s simple Program to implement Binary Search 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 : :


This C program, using recursion, performs binary search. In this program an array of random number is generated. The user is asked to enter a key. The array of random numbers are sorted and then the binary search operation is performed based on the key.

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


SOURCE CODE : :



Output : :
