 C++ Program to reverse number

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.

1. #include <iostream.h>
2. #include <conio.h>  
3. void main()  
4. {  
5. int n, reverse=0, rem;    
6. cout<<"Enter a number: ";    
7. cin>>n;    
8.   while(n!=0)    
9.   {    
10.      rem=n%10;      
11.      reverse=reverse*10+rem;    
12.      n/=10;    
13.   }    
14.  cout<<"Reversed Number: "<<reverse<<endl;     
15. getch(); 
16. }  

Output:

Enter a number: 234  
 Reversed Number: 432
