  • Compare the temporary number with reversed number

  • If both numbers are same, print palindrome number

  • Else print not palindrome number

Code -

#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;  
}
