The expression `x = (x 0) ? x : -x;` is a ternary operator in many programming languages like C, C++, Java, JavaScript, etc. It is a shorthand for an if-else statement.

Here's how it works:

1. The condition `x 0` is checked. If `x` is greater than 0, it is true; otherwise, it is false.
2. If the condition is true, the value after the `?` is returned. In this case, `x` is returned.
3. If the condition is false, the value after the `:` is returned. In this case, `-x` is returned.

So, if `x` is -10, the condition `x 0` is false. Therefore, `-x` is returned, which is `-(-10) = 10`. So, `x` is assigned the value 10.

In conclusion, this expression makes `x` positive if it's negative, and leaves it as it is if it's already positive. It's a way to get the absolute value of `x`.

Question

The expression `x = (x > 0) ? x : -x;` is a ternary operator in many programming languages like C, C++, Java, JavaScript, etc. It is a shorthand for an if-else statement.

Here's how it works:

1. The condition `x > 0` is checked. If `x` is greater than 0, it is true; otherwise, it is false.
2. If the condition is true, the value after the `?` is returned. In this case, `x` is returned.
3. If the condition is false, the value after the `:` is returned. In this case, `-x` is returned.

So, if `x` is -10, the condition `x > 0` is false. Therefore, `-x` is returned, which is `-(-10) = 10`. So, `x` is assigned the value 10.

In conclusion, this expression makes `x` positive if it's negative, and leaves it as it is if it's already positive. It's a way to get the absolute value of `x`.

What does the expression x = (x > 0) ? x : -x; achieve if x's value is -10?
