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]);
a = atoi (argv [2]);
natoi (argv[3]);
r = atof (argv[4])/100;
i = atof(argv[5])/100;
// TODO write your code here
printf("Future Value: $%.2f\n", value)
printf("Present Value: $%.2f\n",…
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.

- (General math) The value of p can be approximated by this series: 4(113+1517+....) Using this formula, write a program that calculates and displays the value of , using 2, 3, and 4 terms of the series.arrow_forwardThe cost of renting a room at a hotel is, say $100.00 per night. For special occasions, such as a wedding or conference, the hotel offers a special discount as follows: If the number of rooms booked at least 10, the discount is 10%; at least 20, the discount is 20%; and at least 30, the discount is 30%. Also if rooms are booked for at least three days, then there is an additional 5% discount. Write a program that prompts the user to enter the cost of renting one room, the number of rooms booked, the number of days the rooms are booked, and the sales tax (as a percent). The program outputs the cost of renting one room, the discount on each room as a percent, the number of rooms booked, the number of days the rooms are booked, the total cost of the rooms, the sales tax, and the total billing amount. Your program must use appropriate named constants to store special values such as various discounts.arrow_forwardRunning 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]); a = atoi (argv[2]); natoi (argv[3]); r = atof (argv[4])/100; i = atof(argv[5])/100; // TODO write your code here printf ("Future Value: $%.2f\n", value) printf("Present Value: $%.2f\n",…arrow_forward
- 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 the distance that a sound wave will travel in the medium.

- Body 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_forwardBody mass index (BMI) is a measure of health based on weight. It can be calculated by taking your weight in kilograms and dividing it by the square of your height in meters. Write a program that prompts the user to enter a weight in pounds and height in inches and displays the BMI. Note that one pound is 0.45359237 kilograms and one inch is 0.0254 meters.arrow_forwardAverage acceleration is defined as the change of velocitydivided by the time taken to make the change, as given by the following formula: a =v1 - v0 /t Write a program that prompts the user to enter the starting velocity v0 in meters/second, the ending velocity v1 in meters/second, and the time span t in seconds,then displays the average acceleration.
