Structured Programming

Structured programming builds every program from three control structures: sequence, selection and iteration. Grade 11 combines and nests them for real problems.

An array stores many related values under one name, accessed by an index. Loops process arrays to search, total, count and sort.

Strings hold text. Delphi's string functions let you validate, search and transform input — essential for exam questions and real programs.

Procedures and functions break a program into named, reusable blocks — the essence of modular, maintainable code.

Good practical marks come from planning AND testing. Apply IPO and trace tables to design, then test deliberately with well-chosen data.
