What I am confused on is about the isNumPalindrome() function. It returns a boolean value of either true or false. How am I suppose to use that so I can display if it's a palindrome or not. For ex. if (isNumPalindrome == true) cout << "Your number is a palindrome"; else cout << "your number is not a palindrome.";
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
#include <iostream>
#include <cmath>
using namespace std;
int askNumber();
bool isNumPalindrome();
int num, pwr;
int main()
{
askNumber();
return 0;
}
bool isNumPalindrome()
{
int pwr = 0;
if (num < 10)
return true;
else
{
while (num / static_cast<int>(pow(10.0, pwr)) >=10)
pwr++;
while (num >=10)
{
int tenTopwr = static_cast<int>(pow(10.0, pwr));
if ((num / tenTopwr) != (num% 10))
return false;
else
{
num = num % tenTopwr;
num = num / 10;
pwr = pwr-2;
}
}
return true;
}
}
int askNumber()
{
cout << "Enter an integer in order to determine if it is a palindrome: " ;
cin >> num;
cout << endl;
if(isNumPalindrome(num))
{
cout << "It is a palindrome." ;
cout << endl;
}
else
{
cout << "It is not a palindrome." ;
cout << endl;
}
return num;
}
