9. Example of A Flowchart (Iteration)
To display first five even number i.e.2,4,6,8,10.
STOP
START
Display N
Is
N>10?
N=2
N=N+2
Yes
No
STEP1: START
STEP2: SET N = 2
STEP3: DISPLAY N
STEP4: INCREASE N BY 2
STEP5: IS N > 10
IF YES GOTO TO STEP6
IF NO, REPEAT STEP 3
STEP6: STOP

To display first five even number i.e.2,4,6,8,10. with Algo and Counter
STOP
START
Display N
Is C
>5?
N=2
C=1
N=N+2
C=C+1
Yes
No
STEP1: START
STEP2: SET N = 2 & C=1
STEP3: DISPLAY N
STEP4: INCREASE N BY 2 and C by 1
STEP5: IS C > 5
IF YES GOTO TO STEP6
IF NO, REPEAT STEP 3
STEP6: STOP
