write a program is to define macros to find the volume of sphere for radius values ranging from 1 to 10 in tabular form.

Expert Solution

Step 1

Explanation:
The given C++ program calculates the volume of sphere.

Defining an object-like macros i.e.
#define pi 3.14
Defining a function-like macros i.e.
#define VOL( x ) ( 4.0 / 3 ) * pi * ( x * x * x )
Variable r is declared to store the value of radius.
printf (): used to print the data onto output screen.

Approach:

Import the essential header.
Define pi and VOL(x) as macros.
Defining the main method.
Declaring the variables as per the requirement.
Calculate the volume of sphere using macros expansion.
Finally, print the output.
