The standard flowchart symbols and how to write pseudocode, with a worked example that checks odd or even.

Plain-language "code" that shows the logic without a specific programming language.

START
INPUT number
IF number mod 2 = 0 THEN
    OUTPUT "Even"
ELSE
    OUTPUT "Odd"
END IF
END

Why plan first? A flowchart or pseudocode lets you find mistakes in your thinking before you spend time typing real code.
