Hello, I have this program to do and I'm completely clueless on how to get started. Any suggestions will be greatly appreciated.

Write a program to convert Celsius to Fahrenheit or Fahrenheit to Celsius depending on the user’s choice.
a. Use main( ) as the driver function. main( ) should allow the user to run the program as many times as desired.
b. Write the function getConvertChoice( ) to prompt the user for the desired conversion:
1. Celsius to Fahrenheit
2. Fahrenheit to Celsius.
Return this value back to main( ).
c. Write the function getTemperature( ) to prompt the user for the temperature in degrees to be converted.
d. Depending on the user’s conversion choice: 1) call the function convertToFahren( ), if the user chose to convert from Celsius to Fahrenheit, or 2) call the function convertToCelsius( ) if the user chose to convert from Fahrenheit to Celsius. The formulas are:
Fahrenheit = (9.0/5.0) * Celsius + 32.0
Celsius = (5.0/9.0) * (Fahrenheit – 32.0)
e. Write the function displayConversion( ) to display the original temperature entered and the converted temperature with appropriate messages. Display the values to a tenth of a decimal.
