Note: The Linux packages above are compressed archives (tar, tar.xz or tar.bz2). When you decompress the package you downloaded on your system, you will find all the .rpm or .deb packages required to install Code::Blocks.

Note: On RedHat/CentOS older revisions of 6 (up to 6.2 as far as we know) you need to add repoforge (former rpmforge) to your repolist, to be able to install the needed wxGTK-package. See https://repoforge.org/use for an instruction.

Note: Redhat/CentOS probably also needs an installed hunspell-package, if you want to install the contrib-plugins.

Code::Blocks là gì?

Đây là môi trường phát triển tích hợp (IDE) miễn phí được xây dựng để đáp ứng các nhu cầu khắt khe nhất của người dùng trong lập trình các phần mềm được viết bằng ngôn ngữ C, C++ hoặc Fortran. Nó có thể hoạt động được trên nhiều nền tảng như MacOS, Linux hoặc Windows và hỗ trợ nhiều trình biên dịch như MS Visual C++ và GNU GCC.

Bên cạnh đó, Code::Blocks còn có giao diện thân thiện, tổ hợp tính năng đa dạng và có thể dễ dàng thêm các tính năng mới. Điều này có được là do thiết kế trên khung plugin cho phép FDE này mở rộng tính năng bằng cách cài đặt hoặc viết các mã plugin. Ví dụ như chức năng biên dịch và gỡ lỗi trên Code::Blocks được bổ sung bởi các plugin.

Introduction to Programming Languages/Scoping with Blocks

Blocks are a way of solving the scoping problem. A block is a program region containing definitions of variables and that delimits the regions where these definitions apply. In programming language, a block is created using a pair of curly braces. The beginning of the block is denoted by an open curly brace ‘{‘ and the end is denoted by a closing curly brace ‘}’. The block collects statements together into a single compound statements. The code below shows two blocks. One of them defines the scope of the main function while the other (an inner block) creates a new scope inside this function. It is possible to see the definition of two variables with the same name, but inside distinct blocks.

#include

int main() { int n = 1; { int n = 2; printf(“%d\n”, n); } printf(“%d\n”, n); }

The scope of a definition is the block containing that definition, from the point of definition to the end of the block, minus the scopes of any redefinitions of the same name in interior blocks. So, the scope of the variable ‘n’, defined in the line 3, begins at that line and ends at line 9. But, because there is a new definition of a variable named ‘n’ inside this block, the variable ‘n’ defined outside the inner block becomes hidden from line 5 to line 7. The same source code is presented below with the distinction of the visibility of the two variables named ‘n’. The scope visibility of the first definition is represented by the letter ‘A’ while the scope visibility of the second definition is represented by the letter ‘B’.

#include

int main() { int n = 1; A { A int n = 2; B printf(“%d\n”, n); B } B printf(“%d\n”, n); A } A

Many different constructs serve as blocks in different languages. The term block-structured is commonly referred to languages that use some kind of block to delimit scope. Nowadays, the majority of programming languages are block-structured and few people bother to make this distinction.

The ML programming language uses the

let

construct to define a block. The following source code shows an example of it use. The

let

construct contains definitions (located before the keyword ‘in’) and a region where those definitions apply (from the point of each definition to the final end). The letters ‘A’ and ‘B’ distinct the two scopes in the source code.

let A val n = 1 A val x = n + 1 A in A let B val n = 2 B in B n + x B end B end A

Free configurable IDE

Code:: Blocks is a free and open-source integrated development environment designed for programmers. This development tool offers a wide range of codes and project features that help users develop applications and plugins. The app uses C, C++, and Fortran coding languages and operates as a GUI tool.

What makes Code:: Blocks unique is that it focuses on a plugin-based extension platform. With this, users can create the software the way they want to. Not only that, but compared to other IDEs, such as Microsoft Visual Studios, Eclipse, and Clion, this app is easier to use and runs more smoothly.

What is Code:: Blocks?

As mentioned, Code:: Blocks is the perfect resource for programmers and developers who want to create applications and plugins. It contains much more than what usual IDEs have to offer. It offers project templates, which you can use to create your app. These projects are left blank, giving you the creative freedom to write your application however you want. You can use the suggestions and tools that the app provides, but you can also work your way through your codes on your own.

Blocks also come with a useful line duplicating feature, allowing you to save time as you write your codes. With this, you can repeat the same codes several times in the project without rewriting them. The lines can also be edited easily and quickly, making the whole process seamless. Furthermore, the app allows you to get support for multi-threading with its debugging tool. Instead of picking layers apart to debug your project, this app digs into the code to resolve the issue.

For major developers, Blocks has a strong inter-project dependency setup. With this, you can see how different parts affect each other. It also lets you see how your references might be interconnected. Additionally, the program utilizes parallel builds and full break-point support. Another helpful feature is code completion, which aids with the tedious work of correcting code mistakes or recalling keywords that you cannot fully remember.

How do you use Code::Blocks?

Installing the app on your computer is not a complicated process. However, setting it up can be a hassle for beginners. To begin with, you will have to select a compiler. Don’t worry, though, since you can download and link to any compiler you would like. The next step is to choose the debugger path. Then, you will choose the programming language the code will be in—either C or C++. Note that you need to ensure that the compiler supports the language you selected.

All proper debugging and files should fall under a project that you will have to create. You should also note that only toy programs can be done outside an operation. Also, you won’t have access to the debugger in these environments. However, when you do create a project, it will come with everything you need. From relevant information to source codes and header files, everything is within this compilation. Debugging will be your next and final step once you are done creating your project.

Despite being one of the easier-to-use tools, however, Code:: Blocks still requires significant knowledge from the users. All of the Qt tools need to be pre-installed, and unless you are well-versed in programming, this can be time-consuming and difficult. The coding is also dense to read, making it difficult to pick out specific lines of codes. Additionally, the app is limited because the system is becoming more and more outdated, even with the newer versions.

Another thing to note is that the code completion does not work as intended and more work is required for the user to ensure that the code is done. It is a pity since most IDEs ship with some form of code completion. Moreover, you cannot keep two toy programs within a single project. Only one main function file is allowed in tandem within the individual system, making the app inefficient for larger projects, such as corporate software or video games.

Still a good tool for small projects

Overall, Code::Blocks is a helpful and innovative program for developers and programmers. With this, you can create Qt applications and plugins with ease. However, it comes with various limitations and has a bit of a clumsy feel to it. It also inefficient for larger projects. Nevertheless, it is suitable for smaller projects and provides you with all the resources to help you build.

Block Coding in Digital Electronics

Block coding is a method used in digital electronics to encode data into a specific format. The purpose of block coding is to add redundant information to the data, which can be used to detect and correct errors that may occur during transmission or storage. Block coding is often used in conjunction with error correction codes (ECCs) to provide a more robust way of transmitting and storing data.

There are several types of block codes, including:

  1. Hamming Codes: Hamming codes are a type of block code that can detect and correct single-bit errors. They are commonly used in digital systems to ensure the accuracy of transmitted data.
  2. Reed-Solomon Codes: Reed-Solomon codes are a type of block code that can correct multiple-bit errors. They are commonly used in storage systems, such as CD-ROMs and DVDs, to ensure the integrity of stored data.
  3. BCH Codes: BCH codes are a type of block code that can correct a specific number of errors. They are commonly used in digital communication systems to ensure the accuracy of transmitted data.
  4. Block coding can provide many benefits in digital electronics, including improved reliability, increased data accuracy, and greater efficiency in the transmission and storage of data. However, block coding also has some disadvantages, including increased complexity and increased overhead in terms of processing time and memory usage.

In summary, block coding is a method used in digital electronics to encode data into a specific format, adding redundant information to the data to detect and correct errors that may occur during transmission or storage. There are several types of block codes, including Hamming codes, Reed-Solomon codes, and BCH codes, and they offer many benefits in terms of data accuracy and reliability, but also come with some disadvantages, such as increased complexity and overhead.

Conversion of Digital Data to Digital Signal involves three techniques:

  1. Line Coding
  2. Block Coding
  3. Scrambling

Out of which Line coding is always needed, block coding and scrambling may or may not be needed. Block coding helps in error detection and re-transmission of the signal. It is normally referred to as mB/nB coding as it replaces each m-bit data group with an n-bit data group (where n>m). Thus, its adds extra bits (redundancy bits) which helps in synchronization at receiver’s and sender’s end and also providing some kind of error detecting capability. It normally involves three steps: division, substitution, and combination. In the division step,a sequence of bits is divided into groups of m-bits. In the substitution step, we substitute an m-bit group for an n-bit group. Finally, the n-bit groups are combined together to form a stream which has more bits than the original bits. Examples of mB/nB coding: 4B/5B (four binary/five binary ) – This coding scheme is used in combination with NRZ-I. The problem with NRZ-I was that it has a synchronization problem for long sequences of zeros. So, to overcome it we substitute the bit stream from 4-bit to 5-bit data group before encoding it with NRZ-I. So that it does not have a long stream of zeros. The block-coded stream does not have more than three consecutive zeros (see encoding table). At the receiver, the NRZ-I encoded digital signal is first decoded into a stream of bits and then decoded again to remove the redundancy bits. Drawback – Though 4B/5B encoding solves the problem of synchronization,it increases the signal rate of NRZ-L.Moreover,it does not solve the DC component problem of NRZ-L. 8B/10B (eight binary/ten binary) – This encoding is similar to 4B/5B encoding except that a group of 8 bits of data is now substituted by a 10-bit code and it provides greater error detection capability than 4B/5B. It is actually a combination of 5B/6B and 3B/4B encoding.The most five significant bits of a 10-bit block is fed into the 5B/6B encoder; the least 3 significant bits is fed into a 3B/4B encoder. The split is done to simplify the mapping table. A group of 8 bits can have 2^8 different combinations while a group of 10 bits can have 2^10 different combinations. This means that there are 2^10-2^8=768 redundant groups that are not used for 8B/10B encoding and can be used for error detection and disparity check. Thus, this technique is better than 4B/5B because of better error-checking capability and better synchronization. Reference- Data Communications and Networking By Behrouz A.Forouzan(Book)

Advantages of Block Coding in Digital Electronics:

  1. Improved Reliability: Block coding can improve the reliability of digital systems by adding redundant information to the data, which can be used to detect and correct errors that may occur during transmission or storage.
  2. Increased Data Accuracy: Block coding can help ensure the accuracy of transmitted or stored data by detecting and correcting errors that may occur.
  3. Greater Efficiency: Block coding can increase the efficiency of digital systems by reducing the number of errors that occur during transmission or storage, reducing the need for retransmission or storage.
  4. Robustness: Block coding can provide a more robust way of transmitting and storing data by detecting and correcting errors that may occur, reducing the impact of errors on the overall system.

Disadvantages of Block Coding in Digital Electronics:

  1. Increased Complexity: Block coding can increase the complexity of digital systems, making them more difficult to design, implement, and maintain.
  2. Increased Overhead: Block coding can increase the overhead of digital systems in terms of processing time and memory usage, reducing overall system performance.
  3. Increased Cost: Block coding can increase the cost of digital systems, as it requires additional hardware or software to implement the error correction and detection mechanisms.

Downloads

There are different ways to download and install Code::Blocks on your computer:

  • Download the binary release

    This is the easy way for installing Code::Blocks. Download the setup file, run it on your computer and Code::Blocks will be installed, ready for you to work with it. Can’t get any easier than that!

    • Download a nightly build

      There are also more recent so-called nightly builds available in the forums. Please note that we consider nightly builds to be stable, usually, unless stated otherwise.

    • Other distributions usually follow provided by the community (big “Thank you!” for that!). If you want to provide some, make sure to announce in the forums such that we can put it on the official C::B homepage.

  • Download the source code

    If you feel comfortable building applications from source, then this is the recommend way to download Code::Blocks. Downloading the source code and building it yourself puts you in great control and also makes it easier for you to update to newer versions or, even better, create patches for bugs you may find and contributing them back to the community so everyone benefits.

  • Retrieve source code from SVN

    This option is the most flexible of all but requires a little bit more work to setup. It gives you that much more flexibility though because you get access to any bug-fixing we do at the time we do it. No need to wait for the next stable release to benefit from bug-fixes!

    Besides Code::Blocks itself, you can compile extra plugins from contributors to extend its functionality.

Thank you for your interest in downloading Code::Blocks!

Blocks

A sequence of declarations, definitions, and statements enclosed within curly braces ({ }) is called a “block.” There are two types of blocks in C. The “compound statement,” a statement composed of one or more statements (see The Compound Statement), is one type of block. The other, the “function definition,” consists of a compound statement (the body of the function) plus the function’s associated “header” (the function name, return type, and formal parameters). A block within other blocks is said to be “nested.”

Note that while all compound statements are enclosed within curly braces, not everything enclosed within curly braces constitutes a compound statement. For example, although the specifications of array, structure, or enumeration elements can appear within curly braces, they are not compound statements.
