Question

This assignment is mainly to practice Iteration ( we review this week) and Selection programming structures. That is a FOR loop and IF ... THEN ... ELSEIF ... ELSE ... END IF structures.

Open a blank file (use Word or a text editor). Type your name and CS 3 in the beginning of the file.

Save the file as yourlastname-firstname-ProgIteration.docx or save the file as yourlastname-firstname-ProgIteration.txt. Preferably in CS 3 folder that you already created other assignments.

What is the output of the following code, what values of I and HowMuch will be displayed.

DIM i AS INTEGER

DIM HowMuch AS INTEGER

HowMuch = 0

FOR i = 1 TO 10

IF i < 5 THEN

HowMuch = HowMuch + 1

ELSEIF i = 5 THEN

HowMuch = HowMuch - 5

ELSE

HowMuch = HowMuch + 3

END IF

PRINT i, HowMuch

NEXT i

PRINT HowMuch

Answer 1

The output of the following program will be

1 1
2 2
3 3
4 4
5 -1
6 2
7 5
8 8
9 11
10 14
14

The step by step explanation is as follows:

Initially we have defined HowMuch to 0, and then we are iterating i from 1 to 10.

When i is 1, the first if loop is executed, so 1 is added to Howmuch, so Howmuch will be 1 and the value of i and HowMuch is printed.

When i is 2, the first if loop is executed, so 1 is added to Howmuch, so Howmuch will be 2 and the value of i and HowMuch is printed.

When i is 3, the first if loop is executed, so 1 is added to Howmuch, so Howmuch will be 3 and the value of i and HowMuch is printed.

When i is 4, the first if loop is executed, so 1 is added to Howmuch, so Howmuch will be 4 and the value of i and HowMuch is printed.

When i is 5, the else if loop is executed, so 5 is subtracted from Howmuch, so Howmuch will be -1 and the value of i and HowMuch is printed.

When i is 6, the first if loop is executed, so 3 is added to Howmuch, so Howmuch will be 2 and the value of i and HowMuch is printed.

When i is 7, the first if loop is executed, so 3 is added to Howmuch, so Howmuch will be 5 and the value of i and HowMuch is printed.

When i is 8, the first if loop is executed, so 3 is added to Howmuch, so Howmuch will be 8 and the value of i and HowMuch is printed.

When i is 9 the first if loop is executed, so 3 is added to Howmuch, so Howmuch will be 11 and the value of i and HowMuch is printed.

When i is 10, the first if loop is executed, so 3 is added to Howmuch, so Howmuch will be 14 and the value of i and HowMuch is printed.

and after the for loop is completed, the value of HowMuch is printed. so the final printed value is 14.
