Problem statement

Employee monthly pay slip When supplied employee details: 
first name, last name, annual salary (positive integer) and super rate (0% - 50% inclusive), payment start date, 
The program generates pay slip information with name, pay period, gross income, income tax, 
net income and super. 
The calculation details will be the following: 
• pay period = per calendar month 
• gross income = annual salary / 12 months
• income tax = based on the tax table provided below
• net income = gross income - income tax
• super = gross income x super rate
Notes: All calculation results should be rounded to the whole dollar. 
If >= 50 cents round up to the next dollar increment, otherwise round down.

The following rates for 2017-18 apply from 1 July 2017:

Taxable income	Tax on this income
$0 - $18,200	Nil
$18,201 - $37,000	19c for each $1 over $18,200
$37,001 - $87,000	$3,572 plus 32.5c for each $1 over $37,000
$87,001 - $180,000	$19,822 plus 37c for each $1 over $87,000
$180,001 and over	$54,232 plus 45c for each $1 over $180,000

For example, the payment in March for an employee with an annual salary of $60,050 and a super rate of 9% is:

• pay period = Month of March (01 March to 31 March)

• gross income = 60,050 / 12 = 5,004.16666667 (round down) = 5,004

• income tax = (3,572 + (60,050 - 37,000) x 0.325) / 12 = 921.9375 (round up) = 922

• net income = 5,004 - 922 = 4,082

• super = 5,004 x 9% = 450.36 (round down) = 450

Below is the input and output format:
