FIGURE $5-24$ Sequence structure

Modular design is a simplified expression of a

using three building blocks called sequence,

selection, and iteration. Each logical structure

must have a single entry and exit point.

Task $2$: Draw a Modular Design for the same

above Home Furnishing Superstore ordering

system scenario.
