C++ Program/Code to input a no. & print its reverse.

//In this program code the user will be prompted to enter a number (integer), and the program will //print the reverse of that.

#include<iostream>      //For Input/Output Stream
#include<conio.h>        //For clrscr & getche
using namespace std;   //using the standard namespace
void main()
{
clrscr();                         //clearing the console screen
long int x,y,s=0;            //value of 's' is initialized with a value of '0'
cout<<"Enter no.:";
cin>>x;                          //user input the value of 'x'
while(x!=0)                   //run until the value of 'x' is not equal to '0'
{
y=x%10;                       //getting the remainder from 'x' when divided by '10' & storing it into 'y'
x=x/10;                          //dividing the value of 'x' by '10' & storing the quotient (integer) in 'x'
s=s*10+y;                      //storing the reversed weighted result in 's'
}
cout<<"\nThe reverse no.="<<s; //printing the reversed number
getche();                        //to exit the program after a keystroke
}
