(Salesperson Salary Ranges) Use a one-dimensional array to solve the following problem. A company pays its salespeople on a commission basis. The salespeople each receive $200 per week plus 9 percent of their gross sales for that week. For example, a salesperson who grosses $5000 in sales in a week receives $200 plus 9 percent of $5000, or a total of $650. Write a program (using an array of

counters) that determines how many of the salespeople earned salaries in each of the follow- ing ranges (assume that each salesperson’s salary is truncated to an integer amount):

a) $200–299
b) $300–399
c) $400–499
d) $500–599
e) $600–699
f) $700–799
g) $800–899
h) $900–999
i) $1000 and over

Enter employee gross sales (-1 to end): 10000
Employee Commission is $1100.00
Enter employee gross sales (-1 to end): 4235
Employee Commission is $581.15
Enter employee gross sales (-1 to end): 600
Employee Commission is $254.00
Enter employee gross sales (-1 to end): 12500
Employee Commission is $1325.00
Enter employee gross sales (-1 to end): -1
Employees in the range:
$200-$299 : 1
$300-$399 : 0
$400-$499 : 0
$500-$599 : 1
$600-$699 : 0
$700-$799 : 0
$800-$899 : 0
$900-$999 : 0
Over $1000: 2
