    Study Notes

    Flowchart Symbols and Applications

    • Process Symbol: Represents a computation. The label uses a verb like "Compute" followed by "what" to compute and "how" to compute. The computer relies on correct instructions.
      • Example 1: To calculate calculateNumber, multiply inputNumber by 2.
      • Example 2: To calculate weeklySalary, multiply hrsWrkd by rateHr.
    • Applying the Process Symbol: Focus on the processing step (item) in the IPO (Input-Process-Output) analysis. Consistency in data representation is crucial.
      • Example 1: To get a result ten times the entered number, multiply the "number" by 10.
      • Example 2: To sum three numbers, add number1, number2, and number3.
      • Example 3: To find the area of a rectangle, multiply length by width.
    • Output Symbol: Similar to the input symbol, but displays known data. Labels use a verb like "print" followed by the data to be displayed.
      • Example 1: Display calculatedNumber.
      • Example 2: Display weeklySalary.
    • Applying the Output Symbol: Focus on the output (item) in the IPO analysis.
      • Example 1: Display the "result".
      • Example 2: Display the "sum".
      • Example 3: Display the "area".

    Flowchart Components (additional symbols)

    • Start/Stop Terminators: Marks the beginning and end of a flowchart.
    • Input/Output Symbols: Represents data entry and display.
    • Process Symbol: Represents the computation of data.

    Flowchart Examples

    • Example 1:

      • Starts with a start terminator.
      • Gets an input ("number").
      • Performs a process: Calculates result as number multiplied by 10.
      • Displays the result.
      • Ends with a stop terminator.

    • Example 2:

      • Starts with a start terminator.
      • Gets three inputs (number1, number2, number3).
      • Performs a process: Calculates the sum as the sum of number1, number2, and number3.
      • Displays the sum.
      • Ends with a stop terminator.

    • Example 3:

      • Starts with a start terminator.
      • Gets inputs length and width.
      • Performs a process: Calculates area as length multiplied by width.
      • Displays the area.
      • Ends with a stop terminator

    Activity

    • Activity #4:
      • Draw flowcharts for:
        • Calculating amount payable (price * quantity).
        • Converting height from feet to inches.

    Additional Flowchart Symbols

    • Decision Symbol: A diamond representing a question or condition with "yes" or "no" outcomes (e.g., if/then statements). Decisions will be included in the later lessons.
    • Connector: Used when a flowchart extends beyond a page. It includes the flow with the same name as the first part, to indicate the continuation.

    Summary of the Course

    • This section covered data types, tools for planning solutions, and flowchart symbols.
    • It also showed how to create flowcharts to represent solutions logically.
