C++ program to display numbers which get reversed after multiplying by 4
#include<iostream.h>
#include<conio.h>
long int revfun(long int a)
{
long int r=0,rem;
while(a>0)
{
rem=a%10;
r=r*10+rem;
a=a/10;
}
return r;
}
void main()
{
clrscr();
for(long int n=1;n<=99999;n++)
{
long int rev=revfun(n);
if(rev==n*4)
{
cout<<n<<endl;
}
}
getch();
}
OUTPUT:
