Check number is palindrome or not
Write a C program to check number is palindrome or not using Recursion. Here’s simple program to check number is palindrome or not 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.
Here is the source code of the C program to check number is palindrome or not using Recursion. The C Program is successfully compiled and run on a Windows system. The program output is also shown below.
SOURCE CODE : :
/* C program to check number is palindrome or not using Recursion */ #include<stdio.h> int checkPalindrome(int); int main(){ int num,sum; printf("Enter any number :: "); scanf("%d",&num); sum = checkPalindrome(num); if(num==sum) printf("\n%d is a palindrome\n",num); else printf("\n%d is not a palindrome\n",num); return 0; } int checkPalindrome(int num){ static int sum=0,r; if(num!=0){ r=num%10; sum=sum*10+r; checkPalindrome(num/10); } return sum; }
Output : :
/* C program to check number is palindrome or not using Recursion */ Enter any number :: 1234321 1234321 is a palindrome Process returned 0
Above is the source code for C program to check number is palindrome or not using Recursion which is successfully compiled and run on Windows System.The Output of the program is shown above .
