Process Symbol Label Structure

In the process symbol label, "Compute" is often followed by the name of the variable being calculated, followed by an explanation of the computation, often using "as" to specify what the computed result will be.

Applying the Process Symbol

The process of using a process symbol to represent a computation. For example, "Compute calculateNumber as inputNumber multiplied by 2" represents multiplying the input number by 2 to calculate the variable 'calculateNumber'.

Process Symbol in Flowcharts

The process symbol helps visualize a computation step in a flowchart, making it easier to understand the logic of the program. It uses the label 'Compute' and then specifies what is being calculated, how it's calculated, and what the result is called.

Consistency in Variable Naming

Ensuring that the same variable name is used consistently throughout the flowcharts and code. For example, if a variable is named "num1" in the input symbol, it should also be named "num1" in the process symbol and any subsequent symbols.

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.
