/* PROGRAM TO REVERSE A FIVE DIGIT NUMBER */

Code: Select all

#include<stdio.h>
#include<conio.h>
main()
{
long int n;
int a;
int rev=0;
printf("Enter the 5 digit number to be reversed\n");
scanf("%d",&n);

a=n%10;

n/=10;     /* i.e, n=n/10 */

Hello friend
find below my program for same function in C++, please comment on it, advice me also.
specially I would like comments from Mr. Praveen.

/* This is a program to reverse any number (digit is not limitation) reverse numbers */

/* n= Given number
r= reverse output
d=constant
*/

#include <iostream>
#include <cmath>

int main ()
{
using namespace std;
int r=0,d,n;
cout << "Enter a value:";
cin >> n;
do
{
d=n%10;
n= n/10;
r=r*10+d;
}
while(n!=0);
{
cout << r << "\n" ;
system ("pause");
return 0;
}

}
