মডুলার প্রোগ্রামিং (Modular Programming)

 

কেবল মাত্র একটি ফাংশন দিয়ে কোনো বড়ো জটিল সমস্যা সমাধানের চেষ্টা করা ভাল প্রোগ্রামিংয়ের পদ্ধতি নয়। সঠিক পদ্ধতি হ'ল সমস্যাটিকে কয়েকটি ছোট ছোট এবং সরল টুকরো করে ফেলা যাতে তা আরও বিশদে বোঝা যায় । তারপরে এই ছোট এবং সরল সমস্যাগুলি সমাধান করার জন্য ছোট ছোট ফাংশন ব্লক তৈরি করা এবং পরে সেগুলি নিয়মানুযায়ী সংযোজিত করা । এতে আরো ভালোভাবে প্রোগ্রামটি বুজতে এবং পরিবর্তন , সংশোধন করতে সুবিধা হয় । প্রতিটি ফাংশন ব্লকে কেবল একটি কাজ ভালভাবে করা উচিত।


As your program continues to grow, you should consider breaking it into several source files, with each source file containing a small group of cohesive functions. Such source files are also called modules. Put data declarations and function prototypes into header files so that any changes to the declarations or prototypes can be automatically signified to all source files that include the header file.

For instance, in the section "Creating a Linked List," all functions that can be used to create a linked list and add or delete a node are put into the same module (24L01.c). Data structure and variable declarations, and function prototypes are saved into a header file (24L02.h). The main() function and the interface are saved into another module (24L03.c).

You can use a software-engineering technique known as information hiding to reduce the complexity of programming. Simply speaking, information hiding requires a module to withhold information from other modules unless it's necessary.

The C compiler enables you to compile and debug different source files separately. In this way, you can focus on one source file at a time, and complete the compiling before you move to the next one. With the separate compilation, you can compile only those source files that have been changed and leave the source files that have already been compiled and debugged unattached.

If you're interested in knowing more about software engineering, study Ian Sommerville's classic book, Software Engineering, which is on the list of recommended books at the end of this lesson.
