C++回文数完整代码

完整代码如下：

#include 
#include 
using namespace std;

bool isPalindrome(int num){
   if (num < 0)
      return false;
   else{
      string s = to_string(num);
      int left = 0, right = s.length() - 1;
      while (left < right){
         if (s[left] != s[right])
            return false;
         else
            left++, right--;
      }
      return true;
   }

}

int main(){
   int num;
   cout << "please enter a number:";
   cin >> num ;
   cout << "the result is:" << isPalindrome(num) << endl;
   system("pause");
}
