Note: Questions 7 - 9 are based on the following pseudo-code. Draw the control flow graph below if this will be helpful.

 

Result = 0

Read (age)

IF Age < 18 THEN

  WHILE Age <> 18 DO

     Result = Result +1

     Age = Age +1

  ENDDO

  Print “You can start driving in {Result} years”

ELSE

  Print “You can start driving now!”

ENDIF
