Answer 6

That code is a calculator
In the flowchart i use looping if the user of the calculator dont input R or D, so calculator says error try again and move to the first section

Answer 7

From main to iferror and vice versa infinitely if user typed Other word instead of 'R' or 'D'

Answer 8

Write
ifError(); inplace of main().

Try to write your own code by this..
Observe that, code written in main method is same in isError() function, so you can delete from main, dublicate code and call isError() method, and if error again call isError() method...
