Question

Consider the following code segment

int value = 15;
while (value < 28) {
.printIn (value);
value++;
}
What are the first and last numbers output by the code segment?
A) 15 and 27
B) 15 and 28
C) 16 and 27
D) 16 and 28
E) 16 and 29

Answer 1

The code segment in question is a while loop from a programming context that prints numbers starting at 15 and increments up to, but not including, 28. Therefore, the first number output is 15 and the last is 27 (Option A).

Step-by-step explanation:

The code provided in the question is from the computer and technology subject area, specifically focusing on programming logic. The while loop begins with the variable value set to 15 and will continue to execute as long as the value is less than 28. On each iteration of the loop, the current value of the value is printed, and then the value is incremented by 1.

The first number printed is the initial value of value, which is 15. The loop runs until a value is no longer less than 28; therefore, the last number printed will be 27, because when the value becomes 28, the condition of the while loop is no longer true, and the loop exits. Hence, the first and last numbers output by the code segment are 15 and 27, respectively.
