Question

Write a simple C program to generate a chart of circle properties. Output chart “iteration” is to be specified by user input. Your chart will include the radius, diameter, circumference, and Area values in a single table, and radius values will range from 0 to 50, floating point values, with three-decimal-place precision. Table should have all column entries right-justified and each column will have a heading above the entries. For example, assuming user enters a incrementation value of 5, the first few entries of the table could look something like:

Radius Diameter Circumference Area

———————————————————————

0.000 0.000 0.000 0.000

5.000 10.000 31.416 78.540

10.000 20.000 62.832 314.159

Use right alignment using printf() Diameter, Circumference, and Area must be used as functions. Output a blank line after every 10 radius entries.
