QUESTION 2: NESTED LOOPS

Company ABC employs a number of salesmen to sell a variety of items. These salesmen earn their income from a commission and are paid based on the items they sell. Company ABC sells several different lines of merchandise
according to grades, namely A, B, C, D and E. Grade A products are difficult to sell (such as a flat screen television) and the salesman receive a higher commission if they sell items from this grade. On the other hand,
products that are graded at E (such as a magazine), are widespread and do not require any creative sales techniques.

Commission is determined as follows:
Grades CommissionGrade A 20% of the total sales
Grade B 18% of the total sales
Grade C 15% of the total sales
Grade D 10% of the total sales
Grade E 5% of the total sales

After the gross salary (i.e. salary before deductions) for each salesman is calculated, a portion of this salary is taxed according to the following tax categories:
Category Current rate Gross salary
Super income tax rate 50% is greater than or equal to R20 000.00
High income tax rate 40% is less than R20 000.00 but greater than or equal to
R15 000.00
Mid income tax rate 30% is less than R15 000 but greater than or equal to
R10 000.00
Low income tax rate 20% is less than R10 000.00 but greater than equal to
R5 000.00
Lowest income tax rate 10% is below R5 000.00

In addition to paying taxes, the salesmen have to contribute a portion of their salary towards their medical aid scheme. Some salesmen qualify for a tax rebate of 50% if their medical aid contribution is greater than or equal to 10% of their gross salary and if their salary is less than R5000.00.

Write a C++ program to determine the tax, gross salary and the final net salary received by each salesman in Company ABC. The program should display these details in the form of a pay slip for each salesman. Additionally
the program should display the total amount in sales made for the month.
The program has the following structure:
· Totals are initialised; totalSales and grossSalary (gross salary for each salesman).
· A prompting message for the number of salesmen at Company ABC.
· A for loop iterating over the number of salesmen.
· Inside this for loop - a prompting message is displayed requesting the user to enter the salesman's staff
number.
· A while loop validates the staff number which can only be between 999 and 9999.
· A prompt for the salesmen's medical aid contribution that will be deducted from each salesman's salary.
· Inside the outer for loop is another inner for loop going from one to five corresponding to the different
grades of products sold. Inside this for loop is a switch statement which is used for prompting the user to input the total sales in rands for each grade of merchandise sold.
· A nested if statement follows to determine the amount of tax that will be deducted from each salesman's salary.
· The tax rebate is determined based on the medical aid contribution.
· A payslip for the salesman is displayed, indicating the gross salary, tax deduction, medical aid contribution deduction and the net salary.
· When the outer for loop is exited, the total sales made for the month is displayed.
A partial implementation of the above program specification is given below. The lines where you have to insert or complete code are indicated in bold.

with the following input:
Enter the number of salesman for Company ABC : 2
Enter the staff number for salesman 1 : 1002
Enter the medical aid contribution for staff number 1002 : R200.00
Enter total sales for Grade A: R20000.00
Enter total sales for Grade B: R1000.00
Enter total sales for Grade C: R1000.00
Enter total sales for Grade D: R2000.00
Enter total sales for Grade E: R2000.00

Enter the staff number for salesman 2 : 1111
Enter the medical aid contribution for staff number 1111 : R3000
Enter total sales for Grade A: R20000.00
Enter total sales for Grade B: R0
Enter total sales for Grade C: R0
Enter total sales for Grade D: R1000.00
Enter total sales for Grade E: R0
The program should displays a pay slip for each salesman #1111 as follows:
.................PAY SLIP.....................
Staff Number : # 1111
Gross Salary : R 4100.00
Tax Deducted : R 205.00
Medical Aid : R 3000.00
Net Salary : R 895.00

Be calm, it looks like you've not deducted 'Medical Aid' from 'Gross Salary' :0

Thanx, I'm having such a tough time with this assignment.

 
 
   netSalary = grossSalary - (tax +medicalAid);


Please look out for more of these. :)
