Answer 1

Because int x has the truth value true, if x is not 0, and false, if x ==0, you can use an int as a condition.

Answer 2

Is that means all statements within the while block will be executed only if the values assigned to the variable x is non-zero?

Answer 3

Yes

Answer 4

But if x ==2, it is not equal to true but it evaluates to true. https://stackoverflow.com/questions/5189072/c-bool-question
