Flowchart CS Thinking Example 1

Follow the full solution, then compare it with the other examples linked below.

Example 1

easy
Name the four standard flowchart symbols and what each represents.

Solution

  1. 1
    Step 1: Oval (rounded rectangle) = Start/End (terminator). Rectangle = Process (an action or calculation).
  2. 2
    Step 2: Diamond = Decision (a yes/no question that creates a branch). Parallelogram = Input/Output (data entering or leaving the system).
  3. 3
    Step 3: Arrows connect the symbols to show the flow of control from one step to the next.

Answer

Oval = Start/End, Rectangle = Process, Diamond = Decision, Parallelogram = Input/Output. Arrows show flow.
Flowcharts use standardised symbols to visually represent algorithms. They are especially useful for showing branching logic and loops in a way that is easy to follow.

About Flowchart

A visual diagram that represents the steps of an algorithm using standard shapes: ovals for start and end, rectangles for processes or actions, diamonds for decisions (yes/no questions), parallelograms for input/output, and arrows to show the flow of execution between steps.
