Functions and Prototypes - Converting Temperatures In this exercise you will create a program that will be used to convert Fahrenheit temperatures to Celsius and Kelvin temperatures through the use of two functions. For this program, assume that temperature will be represented as a double value. Begin by defining the function prototypes for the functions fahrenheit_to_celsius and fahrenheit_to_kelvin which are both passed a double value and return a double value. Now, at the bottom of the file, write the full definitions of both functions. The function fahrenheit_to_celsius is passed a Fahrenheit temperature and returns a rounded Celsius temperature. You may use the function round in order to round the return value. The formula to convert Fahrenheit to Celsius is (5.0/9.0) * (temperature - 32). The function fahrenheit_to_kelvin is passed a Fahrenheit temperature and returns a rounded Kelvin temperature. The formula to convert Fahrenheit to Kelvin is (5.0/9.0) * (temperature - 32) + 273. Remember the rules of PEMDAS when defining the body of your functions. Now, from the temperature_conversion function, declare and initialize the variables celsius_temperature and kelvin_temperature by calling the appropriate functions which you have just defined and passing the variable fahrenheit_temperature. You do not need to declare or initialize fahrenheit_temperature as it is already available to you as a parameter of the temperature_conversion function.

### Transcription of C++ Template for Temperature Conversion Program

This is a code template for creating a simple C++ program that asks the user to enter a temperature in Fahrenheit. The temperature is then passed to a `temperature_conversion` function which computes its equivalent in Celsius and Kelvin using the `celsius_temperature` and `kelvin_temperature` functions.

```cpp
#include <iostream>
#include <cmath>
using namespace std;

//----DO NOT MODIFY THE CODE ABOVE THIS LINE----
//----WRITE YOUR FUNCTION PROTOTYPES BELOW THIS LINE----

//----WRITE YOUR FUNCTION PROTOTYPES ABOVE THIS LINE----
//----WRITE YOUR int main() BELOW THIS LINE----
//----WRITE YOUR int main() ABOVE THIS LINE----
//----DO NOT MODIFY THE CODE BELOW THIS LINE----
void temperature_conversion(double fahrenheit_temperature) {
    //----DO NOT MODIFY THE CODE ABOVE THIS LINE----
    //----WRITE YOUR FUNCTION CALLS BELOW THIS LINE----

    //----WRITE YOUR FUNCTION CALLS ABOVE THIS LINE----
    //----DO NOT MODIFY THE CODE BELOW THIS LINE----
    cout << "The fahrenheit temperature " << fahrenheit_temperature 
         << " degrees is equivalent to " << celsius_temperature 
         << " degrees celsius and " << kelvin_temperature 
         << " degrees kelvin.";
}
//----DO NOT MODIFY THE CODE ABOVE THIS LINE----
```

#### Explanation

- **Include Libraries**: The program starts by including the `<iostream>` and `<cmath>` libraries for input-output operations and mathematical functions respectively.
- **Namespace**: The `std` namespace is used to simplify code writing and eliminate the need for `std::` prefix.
- **Function Prototypes**: You need to define the prototypes for the `celsius_temperature` and `kelvin_temperature` functions between the designated comment lines.
- **Main Function**: The `main()` function, where user input is handled, should be inserted between the provided placeholders.
- **Temperature Conversion**: The `temperature_conversion()` function computes and displays the Celsius and Kelvin equivalents of the Fahrenheit input, utilizing the `celsius_temperature` and `kelvin_temperature` converter functions. Implement these functions and insert their calls where indicated.

Ensure to complete the program by developing the necessary functions and adding appropriate logic within the `main()` to prompt user input.

# Functions and Prototypes - Converting Temperatures

In this exercise, you will create a program that will be used to convert Fahrenheit temperatures to Celsius and Kelvin temperatures through the use of two functions.

For this program, assume that **temperature will be represented as a double value**.

### Step-by-Step Instructions:

1. **Define Function Prototypes:**
   - Begin by defining the function prototypes for the functions `fahrenheit_to_celsius` and `fahrenheit_to_kelvin` which are both **passed a double value** and **return a double value**.

2. **Function Definitions:**
   - At the bottom of the file, write the full definitions of both functions.

3. **fahrenheit_to_celsius:**
   - This function is **passed a Fahrenheit temperature** and **returns a rounded Celsius temperature**. You may use the `<cmath>` function `round` to round the return value.
   - Formula: \( \frac{5.0}{9.0} \times (\text{temperature} - 32) \).

4. **fahrenheit_to_kelvin:**
   - This function is **passed a Fahrenheit temperature** and **returns a rounded Kelvin temperature**.
   - Formula: \( \frac{5.0}{9.0} \times (\text{temperature} - 32) + 273 \).

5. **PEMDAS Rules:**
   - Remember the rules of **PEMDAS** (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) when defining the body of your functions.

6. **Declare and Initialize Variables:**
   - From the `temperature_conversion` function, declare and initialize the variables `celsius_temperature` and `kelvin_temperature` by calling the appropriate functions you have just defined, and passing the variable `fahrenheit_temperature`.

7. **Usage of Parameters:**
   - You do not need to declare or initialize `fahrenheit_temperature` as it is already available to you as a parameter of the `temperature_conversion` function.

This guide provides the necessary steps to create functions that convert temperatures from Fahrenheit to Celsius and Kelvin, emphasizing proper function definition and parameter handling.
