Palindrome String

Write a Program to input a String and check whether it is a Palindrome or not.

#include<iostream> using namespace std; int main() { char str[20],rev[20]; int i,j,k=0,flag=0; cout<<"Enter the string:"; cin>>str; for(i=0;str[i]!='\0';i++); for(j=i;j>0;j--) { rev[j-1]=str[k]; k++; } cout<<"The reverse="<<rev<<"\n"; for(j=0;str[j]!='\0';j++) if(str[j]!=rev[j]) { flag=1; break; } if(flag==0)cout<<"Palindrome\n"; else cout<<"Not Palindrome\n"; return 0; }

Palindrome Number

Write a Program to input a number and check whether it is a Palindrome or not.

#include<iostream> using namespace std; int main() { int num,rev=0,rem=0,n; cout<<"Enter the number:"; cin>>num; n=num; while(n>0) { rem=n%10; rev=rev*10+rem; n/=10; } cout<<"The reverse of "<<num<<" = "<<rev<<"\n"; if(num==rev)cout<<num<<" is a palindrome\n"; else cout<<num<<" is not a palindrome\n"; return 0; }
