C++ Program To Reverse Number

C++ program to reverse number is basically a program that is used to reverse it or in simple words, it can be said that this program can be used to reverse the digits of a provided number.

In this very simple program, the number is first taken from the user as an input and then it is reversed. And this is done very easily in C++ programming language just by the use of arithmetic and loop operators.

Here is an example of a program in C++ language that will clear your concept about the topic and illustrate to you that how a number is reversed:

#include <iostream>  
using namespace std;  
int main()  
{  
int num, rev=0,rem;    
cout<<"Please Enter Your  number : ";    
cin>>num;    
  while(num!=0)    
  {    
     rem=num%10;      
     rev=rev*10+rem;    
     num/=10;    
  }    
 cout<<"Here is the Reversed Number: "<< rev <<endl;     
return 0;  
}  
Output :
Please Enter Your number : 123
Here is the Reversed Number: 321
Output :
Please Enter Your number : 12345
Here is the Reversed Number: 54321
