Write a program that can calculate the future and present value of an investment given
various parameters.
When you calculate the future value of an investment, the more years you hold the
investment and the higher the rate of return, the more valuable it is. For example, a $1000
investment at 7% return will give you $1070 (1000+ 0.07-1000) after one year and
$1144.90 (1070+0.07-1007) after two years.
However, because of inflation, that $1144.90 after two years is not worth the same as
$1144.90 now. If the inflation rate is 2%, $1144.90 in two years is the equivalent of
$1100.44 now-i.e- L02 More generally, the present value, p, of an investment is
1.02²
1144.90
f
p=
where is the inflation rate as a percentage.
Typically, one would add to the investment with annual contributions. Let's say you start
with a $1000 investment and add $100 every year. Therefore, after the first year, you will
have $1177 - 7% return on $1100i.e. $1000 initial investment + the $100 year one
contribution.…
Running the program
Your program should take 5 arguments: start annual years return inflation
where
start is the initial investment amount
annual is the amount that is added to the investment every year
years is the number of years that the investment is held
return is the annual investment return expressed as a percentage
inflation is the annual inflation rate expressed as a percentage
So, to calculate the future and present value of $1000 investment after 10 years where you
add $100 every year with a 7% return and 2% inflation, you give the following arguments
and get this output:
$ ./fv 1000 100 10 7 2
Future Value: $3445.51
Present Value: $2826.52

METHODOLOGY
A bookstore owner wants you to write a program that calculates the gross pay of an employee.
The input to the program is the number of hours the employee works in one week and the employee’s hourly pay rate.
The program is to calculate the employee’s gross pay including the possibility of overtime pay.
Regular pay is the number of hours the employee worked (up to 40 hours) times the hourly rate.
The program is to compute an overtime pay if the employee worked more than 40 hours.
All hours beyond 40 should be multiplied to 1.5 for the OT differential pay
The program should output the worker’s regular pay, overtime time, and the gross pay (sum of the regular pay and overtime pay).

- Car sales commission problem - For each used car a salesperson sells, the commission paid is as follows: $20 plus 30% of the selling price in excess of the cost of the car. Typically, the minimum selling price of the car is the cost of the car plus $200 and the maximum selling price is the cost of the car and $2,000. Write a program that prompts the user to enter the salesperson’s fixed commission, the percentage of the commission, the purchasing cost of the car, the minimum and the maximum amount to be added to the purchasing cost to determine the minimum and the maximum selling price, and outputs minimum and maximum selling price of the car and the salesperson's commission range.
