A user is writing code to calculate the amount of pay for each worker at a company. The pay rate is the same for all workers.
The code will use the formula:
amount_of_pay = number_of_hours × pay_rate
Which of the following should be used in the code to represent pay_rate?

• A.Object
• B.Function
• C.Constant
• D.Array

답을 확인하기

정답:
Explanation:
Because the pay rate is fixed and does not change for all workers, it is best represented as a constant in code. Constants are variables whose values do not change during execution.
“Constants are used in programming to represent fixed values that do not change during the run of a program.” ― CompTIA ITF+ Software Development Guide
Correct answer: C

Question No : 10

Which of the following is used to securely transfer files over the internet?

• A.Compression
