THIS IS C++ PROGRAMMING:

Before starting: Make sure that you understand the following things:

- How to declare a function.

- How to write a function.

- How to call a function, including call function A from function B which is not main function.

QUESTION:

Write a program to take a depth in kilometers inside the earth as input data; calculate and display the temperature at this depth in both degrees Celsius and degree Fahrenheit. The formulas are:

-Celsius temperature at depth in km: celsius = 10 x depth(km) + 20

-Convert celsius to fahrenheit: fahrenheit = 1.8 x celsius + 32

You should have 4 functions in your program.

1.) void print_introduction (){} // prints out information to tell the user what this program does.

2.) double celsius_at_depth (double depth){} // computes and returns the celsius temperature at a depth measured in kilometers.

3.) double celsius_to_fahrenheit (double celsius){} // converts a Celsius temperature celsius to Fahrenheit.

4.) void print_conclusion(double depth){} // display the conclusion that what is the temperature in both Celsius and Fahrenheit at depth of the earth

Additional Requirement:

There is no calculation in main function. The pseudo code steps for main function as follows:

1.) print introduction by calling print_introduction function

2.) ask user to enter the depth

3.) get users input

4.) print out the conclusion by calling print_conclusion function

5.) ask user if he/she wants to continue

6.) get users input

7.) repeat step 2 to step 6 if user picks Y or y

8.) Stop program

All the necessary calculations are done in print_conclusion function. celsius_at_depth and celsius_to_fahrenheit functions are called from print_conclusion function.

There is no calculation in main function. No calling celsius_at_depth or celsius_to_fahrenheit functions in main function.

SAMPLE RUN:

Hello! The program will tell you the temperature of the earth at any depth.

Enter a depth in KM: 10

The temperature of the earth at a depth of 10 KM is 120 in Celsius, and 248 in Fahrenheit.

Would you like to do it again? (Y/N): y

Enter a depth in KM: 20

The temperature of the earth at a depth of 20 KM is 220 in Celsius, and 428 in Fahrenheit.

Would you like to do it again? (Y/N): n

Program ended with exit code: 0
