C++ program to Check Number is Palindrome or not

A Palindrome number is a number that remains the same when its digits are reversed. Like 16461, for example: we take 121 and reverse it, after revers it is same as original.

Steps to write program

Get the value from user.
Reverse it.
Compare it with the number entered by the user.
If both are same then print palindrome
Else print not a palindrome.

Palindrome Number Program in C++ using while loop

#include<iostream.h>
#include<conio.h>

void main()
{
int a,no,b,temp=0;
clrscr();
cout<<"Enter any num: ";
cin>>no;
b=no;
while(no>0)
{
a=no%10;
no=no/10;
temp=temp*10+a;
}
if(temp==b)
{
cout<<"Palindrome";
}
else
{
cout<<"Not Palindrome";
}
getch();
}

Output

Enter any num: 143
Not Palindrome

Output

Enter any num: 141
Palindrome

Palindrome Number Program in C++ using for loop

#include<iostream.h>
#include<conio.h>

void main()
{
int a,no,b,temp=0;
clrscr();
cout<<"Enter any num: ";
cin>>no;
b=no;
for(;no>0;)
{
a=no%10;
no=no/10;
temp=temp*10+a;
}
if(temp==b)
{
cout<<"Palindrome";
}
else
{
cout<<"not Palindrome";
}
getch();
}
