Create a program that will accept a radius value from the keyboard and calculate the Volume of a Sphere and the Surface Area of a sphere. Separate the program into three files. 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.

Set the output to be fixed with a precision of 3 positions to the right of the decimal point. An example of the output for Radius 3.0 is: Volume: 113.097 Area: 113.097

Test the function using a radius of 4.0

Can you help Mme with this, please? especially the part that I highlighted.

Thank you
