- Get the number from user
- Hold the number in temporary variable
- Reverse the number
- Compare the temporary number with reversed number
- If both numbers are same, print palindrome number
- Else print not palindrome number
Let's examine a C program that identifies palindromic numbers. Within this C program, we will prompt the user for an input and verify if the number is a palindrome.
Example
Example
#include<stdio.h>
int main()
{
int n,r,sum=0,temp;
printf("enter the number=");
scanf("%d",&n);
temp=n;
while(n>0)
{
r=n%10;
sum=(sum*10)+r;
n=n/10;
}
if(temp==sum)
printf("palindrome number ");
else
printf("not palindrome");
return 0;
}
Output:
Output
enter the number=151
palindrome number
enter the number=5621
not palindrome number
