Program to check Palindrome or not

0 Suresh Chand June 2, 2021

In this example, We will learn a program to check Palindrome. We will check a number whether it is palindrome or not.

Palindrome Number is a number whose inverse is equal to the original number. Below number is a palindrome number.

151, 232, 1221 are palindrome numbers.

To understand this example, You must have knowledge in following topics

Algorithm

The algorithm of program to check whether number is palindrome or not is given below

Step 1: Start

Step 2: Initialize the variables a, b, c, s = 0

Step 3: Take input from user and assign to a

Step 4: c = a

Step 5: Repeat this STEP if a > 0

           Step 5.1: b = a % 10

           Step 5.2: s = ( s * 10 ) + b

           Step 5.3: a = a / 10

Step 6: IF (s == c) THEN

           Step 6.1: Number is a palindrome

Step 7: ELSE

           Step 7.1: Number is not a palindrome

Step 8: End

Flowchart

The flowchart of program to check whether number is palindrome or not is given below

CODE: Program to Check Palindrome

Now, We will look on the code to check palindrome.

#include<stdio.h>

void main(){
    
    int a, b, c, s = 0;
    
    printf("Enter a number:\t");
    scanf("%d", &a);
    c = a;

    // the number is reversed inside the while loop.
    while(a > 0){
        b = a % 10;
        s = ( s * 10 ) + b;
        a = a / 10;
    }

    // here the reversed number is compared with the given number.
    if(s == c)
        printf("%d is a palindrome", c);
    else
        printf("%d is not a palindrome", c);
   
}

The output of above program is

Enter a number: 151
151 is a palindrome

Enter a number: 12
12 is not a palindrome
