Modules are a level higher than functions. That's a good start. Think of a function as a unit of work that does something and when you have several functions that you can group in a certain way, you put them in a module.

Sep 7, 2018 · Modular programming is the process of subdividing a computer program into separate sub-programs. A module is a separate software component. It can often be used in a variety of applications and functions with other components of the system.

Jul 6, 2013 · Today I discuss best practice in designing and implementing modules in C (and C++). The most important aspect is that each module should have a simple, well-defined interface given by its header file. Last year I talked about how crucial the principle of divide and conquer is to software design (see Handling Software Complexity).

Jul 22, 2009 · Create header files which contain ONLY what is necessary to use a module. In the corresponding .c file(s), make anything not meant to be visible outside (e.g. helper functions) static. Use prefixes on the names of everything externally …

The modules obtained by this method are typically functional, i.e., the purpose of a module is to take care of a particular functionality of the application. Functional modules obtained by top-down design tend to be particular to the application in

This chapter introduces the principles of modular design, describes the syntax for defining a module in the C language, shows how to pass data from one module to another, suggests a walkthrough table structure for programs composed of several modules and includes an example that validates user input.

Functions are the building blocks of modular programming. They encapsulate a specific task or calculation, making your code more organized and easier to understand. Let’s look at how to create and use functions effectively: A typical function consists of the following components: Here’s a basic example of a function in Python:

Aug 23, 2019 · This paper explains how C programs can be structured by modules. Modularization is a method to organize large programs in smaller parts, i.e. the modules. Every module has a well defined interface toward client modules that specifies how "services" provided by this module are made available.

In C, functions are our way to create modules. A small module may be a single function. A medium-sized module may consist of a group of functions together with global data structures, collected in a single file. A large module may include multiple medium-sized modules.

In this tutorial, we will explore techniques for organizing code into modules and building modular C programs. Code organization involves structuring your codebase in a way that promotes modularity, reusability, and maintainability.
