Question

write a program to check a number is palindrome or not​

Answer 1

Answer:

C Program to Check Whether a Number is Palindrome or Not

In this example, you will learn to check whether the number entered by the user is a palindrome or not.

To understand this example, you should have the knowledge of the following C programming topics:

C Programming Operators

C if...else Statement

C while and do...while Loop

An integer is a palindrome if the reverse of that number is equal to the original number.

Program to Check Palindrome

#include <stdio.h>

int main() {

int n, reversedN = 0, remainder, originalN;

printf("Enter an integer: ");

scanf("%d", &n);

originalN = n;

// reversed integer is stored in reversedN

while (n != 0) {

remainder = n % 10;

reversedN = reversedN * 10 + remainder;

n /= 10;

}

// palindrome if orignalN and reversedN are equal

if (originalN == reversedN)

printf("%d is a palindrome.", originalN);

else

printf("%d is not a palindrome.", originalN);

return 0;

}

Output

Enter an integer: 1001

1001 is a palindrome.

Here, the user is asked to enter an integer. The number is stored in variable n.
