The following program uses a variable workHoursPerWeek rather than directly using 40 in the salary calculation expression.

Run the program, observe the output. Change 40 to 35 (France's work week), and run again.

Generalize the program further by using a variable workWeeksPerYear. Run the program. Change 50 to 52, and run again.

Introduce a variable monthlySalary, used similarly to annualSalary, to further improve program readability.

public class Salary {
public static void main (String [] args) {
int hourlyWage = 20;
int workHoursPerWeek = 40;
// FIXME: Define and initialize variable workWeeksPerYear, then replace the 50's below
int annualSalary = 0;

annualSalary = hourlyWage * workHoursPerWeek * 50;
System. out. print("Annual salary is: ");
System. out. println(annualSalary);

System. out. print("Monthly salary is: ");
System. out. println((hourlyWage * workHoursPerWeek * 50) / 12);

return;
}
}

Initial program output (from original program)

Annual salary is: 40000

Monthly salary is: 3333

Program output after workHoursPerWeek = 35

Annual salary is: 35000

Monthly salary is: 2916

Revised program (using variable workWeeksPerYear)

Program output:

Annual salary is: 36400

Monthly salary is: 3033

Revised Program after introducing monthly salary

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.

no, it just either gets automatically 5 points to give away, or u can choose how many points u want to give but, the answerer only gets half

solution:

the right option is a

to adding   a new row to a table we   have to do process last table cell and pressing tab.

this is the process to add new row in the cell:

* to add a row below the cell, click insert below in the rows and columns group.

thus this is the required right answer.
