Given an airplane’s acceleration a and take-off speed v, you can compute the minimum runway length needed for an airplane to take off using the following formula:
length = v2/2a
Write a program that prompts the user to enter v in meters/second (m/s) and the acceleration a in meters/second squared and displays the minimum runway length.
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
Writing the code
Starter code is provided for you below
int main(int arge, char **argv )
{
int a, n
double value, present, I, is
value= atof(argv[1]);

- 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.…arrow_forwardThe following table shows the approximate speed of sound in air, water, and steel:Write a program that asks the user to enter “air”, “water”, or “steel”and thedistance that a sound wave will travel in the medium.

- Average acceleration is defined as the change of velocity divided by the time taken to make the change, as shown in the following formula: a = ( v1 - v0 ) / t Write a program that prompts the user to enter the starting velocity in meters/second, the ending velocity in meters/second, and the time span t inseconds, and displays the average acceleration.arrow_forwardIf you know the balance and the annual percentage interest rate, you can compute the interest on the next monthly payment using the following formula: interest = balance * (annualInterestRate / 1200) Write a program that reads the balance and the annual percentage interest rate and displays the interest for the next month.arrow_forwardBody Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in meters squared. Calculate a persons Body Mass index using their weight in pounds. This means you must first convert pounds to kilograms (kg) then apply the formula above. In converting pounds to kg, 1 pound = 0.453592 kg. So to convert pounds to kg, either multiply the pound value by 0.45359237 or divide by 2.2046226218. Then you must convert their height in inches to meters. The length in meters is equal to the inches multiplied by 0.0254. Write a program that accepts a users height as an integer in inches and their weight in pounds. Convert those inputs to their metric equivalents outlined above and determine their body mass index. Display what the conversions from and to their metric equivalents are. Display the body mass index and the category it belongs to.arrow_forward

You are required to write a program that calculates the occupancy rate and the total hotel income for one night and displays this information as well as some other information described below. The program starts by asking the location where this hotel chain is located and the number of floors in the hotel. The number of floors may not exceed 5. The User then enters the total number of rooms for each floor. The program then asks specifically the number of occupied rooms for each room type on this floor. The total number of rooms on each floor may not exceed 30 and the program should check that the total number of occupied rooms on each floor does not exceed the total of rooms on…arrow_forwardFinancial application: compute future apartment rent) Suppose that the rent for an apartment is $1000 thisyear and increases 3% every year.

The tax percent is 13%. The program calculates the total invoice of the customer after the appropriate discount and the tax amount are applied. The program prints out the customer name (entered by the user), the discounted amount, the tax amount and the total invoice. The program asks if the user wants to continue using the application with a new order (y/n).
