ভালো C প্রোগ্রামিং কিভাবে করবে ?

ক্লাস 24 : তুমি এখন যে গুলি করতে পারো

CLASS 24: What You Can Do Now

You're now in the last chapter of this book. In this lesson you'll learn more about the C language from the following topics:

Programming style
Modular programming
Debugging

Debugging

I've mentioned debugging several times in this lesson. What is a bug, anyway?

A bug in this context refers to any erroneous behavior of a computer system or a software program. Debugging means finding bugs and fixing them. Please be aware that no computer system or software program is immune to bugs. Programmers, like you and I, make bugs, because we're human beings.

When you're debugging your program, learn how to isolate the erroneous behavior performed by your program. Many C compilers provide built-in debuggers that you can use. Also, there are quite a few debugging tools available from third-party software vendors.

As has been said, debugging requires patience, ingenuity, and experience. I recommend that you read a good book that will teach you all the techniques of debugging; in fact, I recommend one in the list of the books in the next section.

মডুলার C প্রোগ্রামিং (Modular C 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 ।

Programming Style

In this section, I'd like to briefly highlight some points that will help you write clean programs that can easily be read, understood, and maintained.

Exercises : Answer the following Question

To help solidify your understanding of this hour's lesson, you are encouraged to answer the quiz questions and finish the exercises provided in the Workshop before you move to the next lesson.

Question and Answer

Q Is the C preprocessor part of the C compiler?

A No. The C preprocessor is not part of the C compiler. With its own line-oriented grammar and syntax, the C preprocessor runs before the compiler in order to handle named constants, macros, and inclusion of files.

Compiling Your Code Under Conditions

Compiling Your Code Under Conditions

You can select portions of your C program that you want to compile by using a set of preprocessor directives. This is useful, especially when you're testing a piece of new code or debugging a portion of code.
