Write a program to take a depth(in kilometers) inside the earth as input data; compute and display the temperature at this depth in degrees celsius and degrees Fahrenheit. The relevant formulas are: Celsius = 10(depth) + 20 (Celsius temperature at depth in km) Fahrenheit = 1.8 (Celsius) + 32 Include two functions in your program. Function celsius_at_depth should compute and return the Celsius temperature at a depth measured in kilometers. Function fahrenheit should convert a celsius temperature to Fahrenheit. 

NOTE: USE C CODE
