A palindrome is a number or a text phrase that reads the same backwards as forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a C++ program that reads in a five-digit integer and determines whether it is a palindrome .

Answer:

#include <iostream>

#include <math.h>
using namespace std;
 
class Point {
   private:
        double x,y,z;
      
   public:
      // required constructors
      Point() {
        x=y=z=0;
      }
      Point(double a,double b,double c) {
        x=a;y=b;z=c;
      }

      // overloaded < operator
      bool operator <(Point& d) {
          double dist1=sqrt(x*x+y*y+z*z);
          double dist2=sqrt(d.x*d.x+d.y*d.y+d.z*d.z);
         if(dist1<dist2)
         return true;
         return false;
      }
            // overloaded > operator
      bool operator >(Point& d) {
          double dist1=sqrt(x*x+y*y+z*z);
          double dist2=sqrt(d.x*d.x+d.y*d.y+d.z*d.z);
         if(dist1>dist2)
         return true;
         return false;
      }
            // overloaded == operator
      bool operator ==(Point& d) {
          double dist1=sqrt(x*x+y*y+z*z);
          double dist2=sqrt(d.x*d.x+d.y*d.y+d.z*d.z);
         if(dist1==dist2)
         return true;
         return false;
      }
      
};

//test them

int main() {
   Point p1(1,1,1),p2(2,2,2),p3(1,1,1);
 
   if( p1 < p2 ) {
      cout << "p1 is less than p2 " << endl;
   } else if(p1>p2) {
      cout << "p1 is greater than p2 " << endl;
   } else if(p1==p2)
   {cout << "p1 is equal to p2 " << endl;}
   
    if( p1 < p3 ) {

   } else if(p1>p3) {
      cout << "p1 is greater than p3 " << endl;
   } else if(p1==p3)
   {cout << "p1 is equal to p3 " << endl;}
   
   return 0;
