Question

Named constants should be used when they serve to improve readability and understanding. T or F

Answer 1

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

Answer 2

It's true. T for true
