Answer:
//here is code in C++.
#include <bits/stdc++.h>
using namespace std;
int main()
{
// variables
int num,num_copy;
int new_num=0;
cout<<"enter a five digit number: ";
// read number from user
cin>>num;
// check input is a 5 digit number or not
while(num<10000||num>99999)
{
cout<<"Wrong input!!"<<endl;
cout<<"enter a five digit number only: ";
// if input is wrong it will again ask user to enter 5 digit number
cin>>num;
}
// make a copy of input number
num_copy=num;
//reverse the digits of input and make a new 5 digit number
while(num>0)
{
int r=num%10;
new_num=new_num*10+r;
num=num/10;
}
// check if both number are same or not
// is same then print palindrome else not palindrome
if(num_copy==new_num)
cout<<"number is palindrome"<<endl;
else
cout<<"number is not palindrome"<<endl;
return 0;
}
Explanation:
Read a five digits number from user.If input is not a five digits number then it will ask again to enter a five digit number until user enter the correct input. Then it make a copy of the input number.It will make a new five digit number by reversing the digits of input number.Then it will match both the number, if they match then it will print "palindrome" else "not palindrome".
<u>Output:</u>
enter a five digit number: 123 Wrong input!! enter a five digit number only: 222221 Wrong input!! enter a five digit number only: 23432 number is palindrome
enter a five digit number: 12345 number is not palindrome
