Can you explain to me

Question

++x + --x what is out of this if x = 6

Answer 1

Hello, that is my favorite operator so let me discuss this:

++x or --x // is Prefix Increment/Decrement

x++ or x-- // is Postfix Increment/Decrement

So:

On Prefix Increment, the interpreter evaluates the operation before the statement.

x = 3
++x // 4
y = ++x + 2 // 6

On postfix - Its almost the same in the Prefix operator, but only in one thing: the operation will only happen after the statement is evaluated.

x = 3
x++ // 4
y = x++ + 2 // 3 + 2 = 5 and now x = 4

Hope this is helpful. This is how JavaScript do Increments and Decrements and I think its the same in the other language.
