Palindrome means a number which remains same if positions of its digits is reversed i.e., 1221 #include<stdio.h> #include<conio.h> void main() { int n,digit,rev=0,num; printf("enter the number"); scanf("%d",&num); n=num; do { digit=num%10; rev=rev*10+digit; num/=10; }while(num!=0); printf("reverse number is=%d\n",rev); if(n==rev) { printf("number is palindrome"); } else { printf("number is not palindrome") ; } getch(); }
