Answer 1

This is the duplicate of https://question.onlinegdb.com/15338/explain-why-the-output-is-didnt-enters-loop

Not a literal duplicate, but the same problem in principles: comparing signed and unsigned numbers.

I did a lengthy explanation in your first question. Please, read it and apply the same logic here.

Answer 2

The answer will be '-1' because -1 is less than 4(size of integer variable)
