|| OR
||
&& AND

3. Flowchart Algorithm Variables
Preparation Ex : 1.)
X = 5 x = 5
CollectMaterialsVariable:X ,Y y = 4 y = 4
Z = X+Y Z = X+Y Z = X+Y
Condition
Is Z lessthan100 ? Yes or No Print ? Is ? lessthan100 ?
Yesor No
If true , re-startthe operation If true , restart
Else if false the operationElse if
false
Display result Display ?
