Study Notes
Sequential Proccessing
- In sequential processing, performing an action or task and then preform the next action in order.
- Sequential processing can be any number of tasks.
- There is no chance to skip any task in sequential processing.
- Once sequential processing is started, it must be continued step-by-step until the sequence ends.
Selection/Decision Processing
- During a selection, a question is asked.
- During a selection, an action is taken based on the answer to the question.
- No matter the path taken, the next task is executed.
Selection Statements
- The selection statements are if, if...else, nested if....else, switch, and case.
- The if selection statement is named a single-selection structure,
- The if selection statement selects or ignores a single action.
- The if...else selection statement is named a double selection structure.
- The if...else selection statement selects an action between two different actions.
- The switch statement is named a multiple-selection structure.
- The switch statement selects among different actions.
If Selection Statements
- Pseudocode example: if student's grade is greater than or equal to 60, print "Passed".
If...Else Selection Statements
- The if...else selection structure allows the programmer to specify that a different action is performed when the condition is true and when the condition is false.
- If a student's grade is greater than or equal to 60, print passed, else print failed.
Nested If...Else Selection
- Nested if...else structure tests multiple cases by placing if...else selection structures inside the selection structure.
Iterative Processing
- Iterative processing is created with repetition statements.
- The iterative processing/repetition statements are: while, do...while, and for.
Iterative Processing: While Loop
- A "while" loop repeats while some condition is satisfied.
- The "while" loop tests its condition at the beginning of every loop
- If the condition is false from the start, the sequence of activities contained in the loop never runs.
Stacking Structures
- Logic problems can be solved using only three structures.
- The the three structures can be combined in an infinite number of ways.
- Attaching structures end-to-end is called stacking.
