Suppose we have these declarations,
int x = -1,y = 0,z = 1;
This Boolean expression is correct and it does what the programmer intends.
x < y < z

Quizplus · Accepted Answer

The expression x < y < z is not correct in C++. It is evaluated as (x < y) < z, which means the comparison between x and y is performed first, resulting in either 0 or 1, and then that value is compared to z. Since -1 is less than 0, the result of the first comparison is 1 (true), and thus the expression becomes 1 < 1, which is false. To compare all three variables, the expression should be written as x < y && y < z.
