Answer
Answer
var i = 123456;
while (i != 0)
{
var mod = i % 10;
Console.WriteLine(mod);
i /= 10;
}
The following could be discussed:
- The code could be put into a method with input parameter
- Recursion could be used, but it would just complicate things without giving any advantage
- Console.WriteLine in between of calculations breaks separation of concerns, so yield with IEnumerable could be used to return the digits
- What if the input number is negative? This case should be expected and handled
