Tools for planning logic before coding.
Pseudocode describes logic in plain structured language independent of syntax; flowcharts show decisions and flow with standard symbols (terminator, process, decision, I/O). They clarify design, aid communication and reveal flaws before coding.

Planning the logic on paper before coding prevents tangled programs and makes it easier to explain an approach to others.

A plain-language description of an algorithm that uses structured steps but not the syntax of a specific language.
When a process has many decisions and branches, because the picture makes the paths and loops easy to follow.
Typical applications include sketching the steps of a login flow before writing code, drawing a flowchart for a machine's start-up sequence and writing pseudocode for a search algorithm in a design review.
Study "Debugging" first (topic 11 of 104 in Software & Computing). It covers the groundwork this topic builds on.
Standard flowchart shapes. Top-down refinement. Trace tables.

The next topic is "Version control with Git", which builds directly on this one.
It is classed as Beginner in Software & Computing (topic 12 of 104). It is an entry-level topic. It relies only on basic school mathematics and the ideas introduced earlier in this discipline.
