Write a program to accept a number and check whether it is a CORONA number or not.
CORONA NUMBER: A number whose all digits are odd.
Example: 3975 – all digits are odd
import java.util.Scanner;
class CoronaNumber
{
public static void main(String args[])
{
Scanner in = new Scanner(System.in);
System.out.println("Enter a number");
int n=in.nextInt();
int flag=1;
//check corona number
int t=n;
while(t>0) // taking out digits
{
int d=t%10;
if(d%2==0)//condition to check even number
{
flag=0;
break;
}
t=t/10;
}
if(flag==1)
System.out.println(n+" is a Corona Number");
else
System.out.println(n+" is not a Corona Number");
}
}
