Study Notes
Importance of Flowcharting
- Flowcharting helps to understand a problem more effectively by drawing pictures, which provide a more complete idea of the situation than text alone.
- Combining pictures with text creates a powerful tool for communication and problem solving.
What is a Flowchart?
- A flowchart is a graphical representation of operations involved in a data processing system.
- Symbols are used to represent particular operations or data.
- Flow lines indicate the sequence of operations (top to down sequence).
Flowchart Components
- Terminal: Start or Stop of program flow
- Input / Output operation
- Connector
- Process to be performed
- Decision / Comparison Operation (one arrow goes in, two go out)
Flowchart Structures
Sequential Structure
- A series of processes that follow in order.
- Example: Washing hair (Wet hair, Apply shampoo, Rinse, ...)
Decision Making Structure
- A condition exists that may change the order or types of processes to be followed.
- Example: IF the light is red THEN I will stop OTHERWISE I will go (Drive Car, Light is No Go, Red?, Yes Stop)
Looping Structure
- Performing the same set of processes a number of times until a STOPPING condition occurs.
- Example: Looping until a certain condition is met.
