Pseudo-Codes and Flow Charts

Pseudo-Code

STEP 1: Input X = 1 and Y = 2

STEP 2: Print X

STEP 3: Let X = X + Y

STEP 4: Let Y = Y + 1

STEP 5: If Y < 11, then return to Step 2

STEP 6: Stop

X	Y	PRINT
1	2	1
3	3	3
6	4	6
10	5	10
15	6	15
21	7	21
28	8	28
36	9	36
45	10	45
55	11	55
66	12

Flow Chart

n	b	Output	n = a
1	10	1	No
2	5	2	No
3	10/3	-	No
4	5/2	-	No
5	2	5	No
6	5/3	-	No
7	10/7	-	No
8	5/4	-	No
9	10/9	-	No
10	1	10	Yes

This shows the multiples of 10.

A specific function can be used to make the algorithm terminate.
