Reverse Number program in C++

This article shows that Reverse Number Program in 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.

C++ Program to swap two numbers with and without third variable.

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;  
    }

Enter a number: 627 
Reversed Number: 726
