Given the expression x = 5 and y = ++x + ++x, what are the final values of x and y?
Question
Given the expression
x = 5
and
y = ++x + ++x
,
what are the final values of x
and y
?
Solution
The expression you've given seems to be in a C-like language, but it's important to note that the "++x" syntax is a pre-increment operation, which means it increments the value of x before the rest of the expression is evaluated.
Let's break it down:
-
We start with x = 5.
-
The first ++x increments x by 1, so x is now 6.
-
The second ++x increments x again, so x is now 7.
-
y is then assigned the value of the sum of the two incremented x values (6 + 7), so y = 13.
So, the final values are x = 7 and y = 13.
