C++ Program to Reverse a Number using while loop

Reverse of number means reverse the position of all digits of any number. For example reverse of 251 is 152

Here is source code of the C++ Program to Reverse a Number using while loop. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

SOURCE CODE : :

/*  C++ Program to Reverse a Number using while loop  */

#include<iostream>
using namespace std;

int main()
{
    int no,rev=0,r,n;

    cout<<"Enter any positive number :: ";
    cin>>n;

    no=n;

    while(no>0)
    {
         r=no%10;
         rev=rev*10+r;
         no=no/10;
    }
    cout<<"\nReverse of a Number [ "<<n<<" ] is :: [ "<<rev<<" ] \n";

    return 0;
}

Output : :

/*  C++ Program to Reverse a Number using while loop  */

Enter any positive number :: 123456

Reverse of a Number [ 123456 ] is :: [ 654321 ]

Process returned 0
