2. Flowchart Algorithm Variables
Preparation ex: 1.) ex: 2.)
x=5 x=5
collect materials x=6 x=6
Variable :x,y z =x+y z =x+y
Condition :
Z = x+y Print ? Is? less than 100% Yes or No
If true, then re-start
The operation
Is Z less than100? Else is fales
Yes or No Display ?
Then End the Operation
If true, re-sport the
Operation Else is false
Display result
Then End operation
Start
INPUT
Process
Condition
