  1. Flowchart Symbols • Terminal • Process • Input/ Output • Decision • Predefined process • Connector • Flow Lines

  2. Control Structures • Sequence Control Structure • Selection Control Structure • Case Control Structure • Iteration Control Structure

  3. 1. Sequence Control Structure Open File Read Record Stmnts -No Decisions -No choices Stmnts

  4. 2. Selection Control Structure IfCondition Yes No Then Stmnts Else Stmnts -paths basedon choices

  5. 3. Case Control Structure Case -More than single Y/N-Replaces many if-then-else Condition P1 P2 P3 P4

  6. 4. Iteration Control Structure Do Until (Print 5 nos.) Do While (Add dept totals) Loop Stmnt Loop Stmnt No Yes Condition Condition -stopping iterations at the beginning-loop after cond. No Yes -stopping iterationsat the end-loop before cond.
