The main program containing the main function should be named main.cpp. The function definition file containing a function for the volume calculation and a function for the surface area calculation should be named SphereCalc.cpp. The function declaration file containing function declarations for the functions should be named SphereCalc.h. Make sure you include a Header Guard. Read the Radius from the Keyboard. If a negative number is provided, set the calculated value to zero.
