QUESTION 9: Below is a tiny computer program written in a "made up" language. Line numbers are added for easy identification; they are not really a part of the program. O BEGIN PROGRAM 1DECLARE VARIABLE x AS INTEGER; 2 3 LET x = 1; 4 5 BEGIN LOOP 6 DISPLAY "Hi there!" ON SCREEN; 7 LET x = x + 3; 8 IF (x IS GREATER THAN OR EQUAL TO y) THEN EXIT LOOP; 9 CONTINUE LOOP 10 PRINT "We are done printing." TO SCREEN; 11 END PROGRAM DECLARE VARIABLE y AS INTEGER; 4 LET y 15; a) What control structure is illustrated by lines 5 through 9? b) What control structure is illustrated by line 8? c) When x is equal to 4, and we are at line 8, what happens next? Explain in detail d) When will the loop end? Explain in detail. e) How many times will "Hi there!" be displayed on the screen? (HINT: It will help to walk through the program - write down the current value of x and whether the message will be printed to the screen. Remember Line 3 sets the initial value of x, then at line 6 we display the message, then at line 7 we change the value of x)
