Question

In the following statement, which operator is used first? whille (K ++ <10).

A. neither
B. the expression is invaild
C. cannot tell without the rest of the code

Answer 1

In the condition 'while (K++ < 10)', the post-increment operator on K is used first, which makes the statement valid and allows us to identify the operator used without additional code.

Step-by-step explanation:

In the condition 'while (K++ < 10)', the post-increment operator on K is used first, which makes the statement valid and allows us to identify the operator used without additional code.

In the statement while (K++ < 10), the operator used first is the post-increment operator (K++). When the condition in the while loop is evaluated, K is compared with 10 before it is incremented. Although this may seem counterintuitive, that is how the post-increment operator works in most programming languages: the value of K is used for the comparison first, and only afterwards is it incremented. Therefore, the correct answer is neither A nor B; rather, the statement is valid, and we can determine the operator used first without the rest of the code.
