The way the current solution is wrote, the same numbers will be generated every-time you run your app.

You should provide a seed to the Random number generator. I usually use (int)DateTime.Now.Ticks.

That is the because a for loop works like this:
1. Initialize (you are assigning a constant of type int (0) to a variable of type a)
2. Check if condition is valid (you are, again, invoking the > operator with an integer (10) and a variable of type a).
3. Increment -> you have your own increment operator defined for a nybble.


For the first one, you are assigning an integer to a Nybble - so the correct implicit conversion kicks in. (The one from int to Nybble)

For the second one, you are using the < operator. The < operator works on operands of the same type. So it will convert 10 to the Nybble type and the call your < operator (the one defined on Nybble).

When the loop "loops" it has to verify that the value of a is smaller than 10. Because 10 is an integer, it will have to apply the implicit conversion from a (which is a Nybble) to int. So your operator gets called.

Does this explain it? If not, could you be more explicit about what your question is? What is it that you find wrong in the output?
