Purpose: The project is designed to ensure that the student know how to write and call functions.

Problem:

Write a program to take a depth (in Kilometers) inside the earth as input data; compute and display the temperature at this depth in degees Celsius and degree Fahrenheit. The relevant formulas are: celcius = 10*depth + 20 (Celsius temperatures are depth in km) fahrenheit = 1.8*clesius +32. You should include four functions in the program.

1. void print_introduction (void)

//prints out information to tell the user what this program does.

2. double_celsius_at_depth (double depth)

//compute 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_conclusions(double depth)

//display the conclusion that what is temperature in Fahrenheit at depth of the earth

Requirement: There is no calculation in main function except function calls to two void functions. The pseudo code for main function is follows:

Step 1: print introduction by calling print_conclusion function

Step 2: ask user to enter the depth

Step 3: get user's input

Step 4: print out the conclusion by calling print_conclusion function

Step 5: ask user if he/she wants to conintue

Step 6: get user's input

Step 7: repeat step 1 to 6 if user picks 'Y' or 'y'

Step 8: stop program

All the necessary calcuations are done in print_conclustion function. i.e. celsius_at_depth and clesius_to_fahrenheit functions are called from print_conclusion function. There is no explicit calculation in main function. No calling to two calculation functions in main function. Run the demo to see the sample output.
