Question 1

Tracing

a	Counter	Sum	Output	Input
		0	Enter a value:	4
4	0	4	Enter a value:	0
0	5	5	Enter a value:	2
2	10		Enter a value:	3
			Enter a value:	0
			Enter a value:	5
			Enter a value:	-6
			Enter a value:	4

Sum 0

Print Enter a value:

Get a

Loop: Counter = 0 To 30 Step 5

If (a != 0)

Sum (Sum + a)

Else

Sum (Sum + 1)

End If

Print Enter a value:

Get a

Loop-End: Counter

a	Counter	Sum	Output	Input
		0	Enter a value:	7
7				0
				0
				3
				3
				0
				0
				4

Print Result is: , Sum

End
