Study Notes

Flowcharting Lesson Notes

Lesson Objective: This lesson focuses on flowcharting as a graphical representation of a program's logical steps. It also covers the practical application of flowcharts
Flowcharting Importance: Flowcharts are crucial for understanding the logic of a program before writing it. They visually map out the steps a computer has to follow, making it easier to identify and fix errors early in the process.
Flowcharting Methods: Flowcharts can be created either freehand or using a template. Freehand is useful if there's no need for a lasting record and for initial versions.
Flowchart Symbols: Specific symbols are utilized for a uniform appearance and understanding. Symbols indicate actions/operations, input/output, decisions, start/end of program, mathematical operations.
Flowcharting Use: Flowcharts aren't the program. They are essential for developing, diagnosing, and documenting a program.
Flowchart Accuracy: It is possible for multiple programmers to develop different flowcharts and programs to solve the same problem.
Program Documentation: Creating complete documentation including the flowchart is crucial. It clarifies exactly what the program does, and aids in understanding.
Flowcharting Learning: Flowcharting is one of the first skills taught in computer programming and can be used to assess a programmer's analytical skills.
Error Detection: If a program has errors, they are more easily detected in a flowchart. This is because a flowchart focuses on logic and is more clear than the program code.
Making Predictions: Predictions rely on an understanding of existing conditions. This understanding allows for better predictions about the future
Types of Predictions: Predictions can be categorized as "certainly," "probability" or "improbable". Different levels of certainty involve percentages
