The code for if a number is neon? Anyone?

Answer 1

I think all don't know about neon number.
A neon number is a number where the sum of digits of square of the number is equal to the number. 
ex
9
9²=81. 8+1=9

cin>>num
no=num*num;
while(no!=0)
{
sum+=no℅10;
no/=10;
}
if(num==sum)
cout<<"neon no.";

Answer 2

The atomic number of Neon is 10, it's a noble gas in the periodic table and therefore is in group 18.
Inorganic chemistry by Walter White

var testElement = 10;
var atomicNe = 10;
if (testElement == atomicNe){
cout<<"The tested element is Neon";
} else {
cout<<"You should be more particular wit your questions!";
}
Edit: pardon my ignorance in the matter, I just learned something new :)
