Chapter 3, Problem 2PP
Write a program to gauge the rate of inflation for the past year. The program asks for the price of an item (such as a hot dog or a one-carat diamond) both one year ago and today. It estimates the inflation rate as the difference in price divided by the year-ago price. Your program should allow the user to repeat this calculation as often as the user wishes. Define a function to compute the rate of inflation. The inflation rate should be a value of type double giving the rate as a percentage, for example 5.3 for

The following formula can be used to determine the distance an object falls due to gravity in a specific time period:
d = 1⁄2 gt2The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the time in seconds that the object has been falling.
Write a function named fallingDistance that accepts an object’s falling time (in seconds) as an argument. The function should return the distance, in meters, that the object has fallen during that time interval. Write a program that demonstrates the function by calling it in a loop that passes the values 1 through 10 as arguments and displays the return value.
In physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy:
KE = 1⁄2 mv2
The variables in the formula are as follows: KE is the kinetic energy in joules, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second.Write a function named kineticEnergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The function should return the amount of kinetic energy that the object has. Demonstrate the function by calling it in a program that asks the user to enter values for mass and velocity.
In physics, an object that is in motion is said to have kinetic energy. The following formula can be
used to determine a moving object's kinetic energy:
KE = ½ m v?
The variables in the formula are as follows: KE is the kinetic energy, m is the object's mass in
kilograms, and v is the object's velocity, in meters per second. Write a function named
kineticEnergy that accepts an object's mass (in kilograms) and velocity (in meters per second) as
arguments. The function should return the amount of kinetic energy that the object has.
Demonstrate the function by calling it in a program that asks the user to enter values for mass and

- 1. A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6.Write a Boolean function named is_prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime.Tip:Recall that the % operator divides one number by another and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2.arrow_forwardIf a year has the digit 7 OR the digit 4 in it, then it is called a “Beautiful year”. For example, 2017, 2014, and 2072 are all beautiful years. If the year has BOTH 4 and 7 in it, then it's an “Amazing year”. For example, the years 2047 and 2074 are amazing years. All other years are “Ugly years”. You need to write a function that takes a year as an argument and return it's type. Then, finally print the returned values in the function call. ================================================ Sample Function Call 1: function_name(2470) Sample Output 1: Amazing year ================================================ Sample Function Call 2: function_name(2170) Sample Output 2: Beautiful year ================================================ Sample Function Call 3: function_name(2021) Sample Output 3: Ugly yeararrow_forwardQ4: the volume of a cylinder is given by the formula: V=r r2L Where r is the cylinder's radius and L is its length.
