Program structure

You’ve been writing flowcharts before you write your programs. This helps ensure that you get all the steps into your program and get them in the right order. Remember that in writing a flowchart you plan the logical flow of your program. Once the flowchart is written, you can translate it into a program by writing one or more statements for each step in the flowchart.

However, when you begin to plan more complex programs, you’ll find that the flowcharts also become more complex. When you have a great many steps and a great many branches, you simply can’t find a place for all of them on the flowchart. This makes it very hard to check the flowchart you’ve written to be sure that you haven’t left anything out. To handle more complex programs, you need another way of planning them. It is modular design.

In engineering, education, programming, and other fields, a module is a self-contained unit that performs one specific task, which is needed to accomplish a larger task. For example, the word module is used in the space program to refer to a part of a spaceship that performs a specific task. A lunar landing module lands on the moon. A power module provides power to the ship in space. A waste-disposal module gets rid of garbage. All of these modules are necessary for getting spaceships to the moon and back.

In a computer program, a module is a self-contained part of the program that performs a specific programming task. For example, a program might have an input module and a print module. A program that is divided into modules in the planning and programming stages has a modular design.

A modular program is said to have a top-down structure because when you plan it, you start at the “top” with the most general module and work your way “down” to include all the modules that make up that module. This allows you to break a complex program into parts to make programming more efficient and easier.
