reverse number using c++

   We can reverse a number in C++ using loop and arithmetic operators. In this program, we are getting number as input from the user and reversing that number.

 Let's see a simple C++ example to reverse a given number.

#include <iostream>  
using namespace std;  
int main()  
{  
int n, reverse=0, rem;    
cout<<"Enter a number: ";    
cin>>n;    
  while(n!=0)    
  {    
     rem=n%10;      
     reverse=reverse*10+rem;    
     n/=10;    
  }    
 cout<<"Reversed Number: "<<reverse<<endl;     
return 0;  
}

Output:

Enter a number: 234  
Reversed Number: 432
