Simple salary calculator

$25$ employees

Name, hourly rates, and hours worked are in a flat file in this format: Last name, first name, hourly rate, hours worked, supervisor email account

For example, a record would look like:

$$Smith$,$ Joe, $15,40,$ lucy$\_$ball@company.com$$

Full$-$time is $40$ hours per week.

For anything over $40$ hours, the employee makes $1\mathrm{.}5$ times their hourly rate.

Overtime should not exceed $50$ hours.

If the employee worked over $50$ hours, an email message must go to the employee$$s supervisor.

Write the results to another file in the following format: Last name, first name, weekly salary, and add a Y or N to the file if the supervisor was sent an email.

For example, the output record would look like:

$$Smith$,$ Joe, $600,$ N$$
