GaryK [48]

Answer:

Point A: Always True

Point B: Sometimes false

Point C: Always False

Explanation:

In the given code snippet. Point A is the first statement within the While loop the statement System.out.println("Welcome to Java!"); will only be executed if the while condition evaluates to true.

At Point B, The statement count++ increases the value of the counter at every iteration, while it will be true for most occasions, at the last increament, this statement will be false that is at count=100, The condition will be false at this point just before program execution breaks out of the loop

Named constants should be used when they serve to improve readability and understanding. T or F
prisoha [69]
The answer is true.

Let's say we are calculating the volume of a grain silo where the the width is a constant, but the height can be changed.

In our code we would calculate the volume using something like:

PI * (WIDTH / 2)^2 * height

The variables in all caps would be named constants. Using them makes the code more readable to other people than if we were to just use their values like:

3.14 * (145.75 / 2)^2 * height
