If originally x=10, what is the value of the expression:--x;Select one:119010

The expression "--x" is a double negation in programming. It means that the value of x is decreased by 1 twice.

Here are the steps to solve it:

1. Start with the original value of x, which is 10.
2. The first decrement operation (--x) decreases the value of x by 1, so x becomes 9.
3. The second decrement operation (--x) decreases the value of x by 1 again, so x becomes 8.

So, the value of the expression "--x" when x originally equals 10 is 8.
