Answer:
Option (c)
Explanation:
Parallel arrays are those arrays which are used to store some records which needs more than one array to hold a entry but are interrelated and should be accessed by same index number. As they are of different data types so can't be stored as multi-dimensional array or matrix. Then parallel array comes to rescue. For example : Details of a student.
Name, age and ID of a student needs to be stored. So, three arrays can be made and each entry should be accessed by same index number.
Answer:
A location in memory which stores a value, the value can change as the program is running is known as a variable.
Answer:
<u> Initial program output (from original program)</u>
Annual salary is: 40000
Monthly salary is: 3333
<u>Program output after workHoursPerWeek = 35</u>
Annual salary is: 35000
Monthly salary is: 2916
<u>Revised program (using variable workWeeksPerYear)</u>
- public static void main(String[] args) {
-
- int hourlyWage = 20;
- int workHoursPerWeek = 35;
- int workWeeksPerYear = 52;
- int annualSalary = 0;
-
- annualSalary = hourlyWage * workHoursPerWeek * workWeeksPerYear;
- System.out.print("Annual salary is: ");
- System.out.println(annualSalary);
-
- System.out.print("Monthly salary is: ");
- System.out.println((hourlyWage * workHoursPerWeek * workWeeksPerYear) / 12);
-
- return;
-
- }
Program output:
Annual salary is: 36400
Monthly salary is: 3033
<u>Revised Program after introducing monthly salary</u>
- public static void main(String[] args) {
-
- int hourlyWage = 20;
- int workHoursPerWeek = 35;
-
- int workWeeksPerYear = 52;
- int annualSalary = 0;
- int monthlySalary = 0;
-
- annualSalary = hourlyWage * workHoursPerWeek * workWeeksPerYear;
- monthlySalary = hourlyWage * workHoursPerWeek * workWeeksPerYear;
-
- System.out.print("Annual salary is: ");
- System.out.println(annualSalary);
-
- System.out.print("Monthly salary is: ");
- System.out.println((monthlySalary) / 12);
-
- return;
-
- }
Explanation:
One reason to use variable to replace the magic number is to improve the readability of the program. If we compared the revised version of the program with the original program, we will find that the variable enable our code easier to understand.
Besides, if we wish to change the value (e.g. working hours per year or per month), we just need to adjust the value assigned on the variables. The variables provide a single access point to get or change the value.
this should help! i read over the article a little bit and it seems to answer your question pretty well. https://www.snap.com.au/articles/the-pros-and-cons-of-digital-and-offset-printing.html
