C++ question using control structures, sequences, selection and repetition

C++ question that relates to the question above, please help

A palindrome is a number or a text phrase that reads the same backward as forward. For example, each of the following five-digit integers is a palindrome: 12321 e 55555 45554 11611 e Write a program that reads in a five-digit integer and determines whether it's a palindrome. The sample output is provided below. Hint: Use the division and modulus operators to separate the number into its individual digits. Enter a five-digit integer 1 to quit): 12 The number 12321 is a palindrome Enter a five-digit integer (or 1 to quit): 12345 The number 12345 is not a palindrome. Enter a five-digit integer (or 1 to quit): 123 The number 123 is not a five-digit number. Enter a five-digit integer (or 1 to quit): -1 Good bye!

Explanation / Answer

PROGRAM CODE:

#include <iostream>
using namespace std;

void isPalindrome(int value)
{
   string textValue = to_string(value) ;
   if(textValue.length()<5)
   {
       cout<<"The number "<<value <<" is not a five-digit number."<<endl;
       return;
   }
   int tempFront = value;
   int tempBack = value;
   int divider = 10000;
   int i=0;
   while(i<3)
   {
       if(tempFront/divider != tempBack%10)
       {
           cout<<"The number "<<value <<" is not a palindrome."<<endl;
           return;
       }
       else
       {
           tempFront = tempFront%divider;
           divider = divider/10;
           tempBack = tempBack/10;
       }
       i++;
   }
  
   cout<<"The number "<<value <<" is a palindrome!"<<endl;
}

int main() {
   while(true)
   {
       int number;
       cout<<" Enter a five-digit number (or -1 to quit): ";
       cin>>number;
       if(number == -1)
           exit(0);
       isPalindrome(number);
   }
  
   return 0;
}

OUTPUT:

PROGRAM CODE:

#include <iostream>
using namespace std;

void isPalindrome(string value)
{
  
   int i=0, j=value.length()-1;
   while(i<value.length())
   {
       while(value.at(i) == ' ')
           i++;
       while(value.at(j) == ' ')
           j--;
       if(value.at(i) != value.at(j))
       {
           cout<<"The word "<<value <<" is not a palindrome."<<endl;
return;
       }
       i++;
       j--;
   }
   cout<<"The word "<<value <<" is a palindrome!"<<endl;
}

int main() {
   while(true)
   {
       string number;
       cout<<" Enter a string (or -1 to quit): ";
       getline(cin,number);
       if(number == "-1")
       {
           cout<<"Good bye!";
           exit(0);
       }
       isPalindrome(number);
   }
  
   return 0;
}
