Question

Based on the following code segment, what is the value of variable z?

var x = "hello";
var y= "world!";
var z = y.length 2 x.length + (3);

Answer 1

The value of variable z can be calculated by first evaluating the expression y.length - 2 * x.length, which involves subtracting twice the length of x from the length of y.

The length of x is 5, and the length of y is 6.

So y.length - 2 * x.length evaluates to 6 - 2 * 5, which is -4.

Then, the expression (3) is simply the number 3.

Adding these two values together gives:

z = -4 + 3 = -1

Therefore, the value of variable z is -1.
