Coding in linux environment

Operating System

As mentioned above, we are gonna be using an OS, which comes under the Linux Distro. There are many popular distro out there, but for starters, Ubuntu is recommended, Kali and Arch Linux are for advance user.
If you are a Windows lover, then stick to Windows 7 or above versions.

Text Editor

Lets set up Geany

Installation

First thing first, we need to install it. You are open to install it either from Ubuntu Software or from the Official Geany Website.
You can also install using the terminal, copy the commands in your terminal:
For Ubuntu/ Debian:-
sudo apt-get install geany
For Fedora:
sudo dnf install geany
For CentOS:
sudo snap install geany-gtk —edge
You can also install plugins

Configure

Once you are done with installation, you can find Geany, using the search bar.

KeyBindings

1. Edit->Preferences->Keybindings
2. Head to focus.
3. Now change the following:
   1. Switch to Editor-> F1
   2. Switch to VTE-> F2

   Terminal

   Build and Compile

   1. First create any C++ file by typing anything in the text editor, and save it by cntrl+s, with a .cpp extension
   2. Head to Build->Set Build Commands
   3. Copy the following flags with the corresponding commands:-
      1. Compile (F8): g++ -std=c++17 -Wshadow -Wall -o «%e» «%f» -O2 -Wno-unused-result
      2. Build (F9): g++ -std=c++17 -Wshadow -Wall -o «%e» «%f» -g -fsanitize=address -fsanitize=undefined -D_GLIBCXX_DEBUG

      You may get compilation error, if so, then try changing from C++17 to C++14, or remove the two sanitizers.

      This is the basic set up for Competitive Programming in a Linux Environment, you can obviously set up another text editor like Sublime, with the other settings as well. I will make a post on that very soon.

      Thank You!
      After complete setup, the environment should look like this:

      Best IDE’s for Linux

      

      I love coding, and ever since the introduction of Integrated Development Environment, also known as IDE, coding has become more of a fun task than a tedious one. IDE’s or Source Code Editors take the task of programming and coding to the next level and make great building applications much easier.

      IDE’s come with many features and plug-ins that help the programmers code the program error or bug-free. There are IDE’s available on Linux and its popularly used distros such as Ubuntu, but I am going to introduce you to the best 10 IDE’s.

      The IDE’s listed below are compatible with coding in various widely-used programming languages like C, C++, and Python. So, let’s get started.

      How to Write, Compile and Run a C Program in Ubuntu and Other Linux Distributions [Beginner’s Tip]

      Running C program in Linux command line is not that difficult. Running it in a code editor like Visual Studio Code is even easier. Learn both methods.

      How do you program in C on Linux? It is indeed very easy and consists of three simple steps. Step 1: Write your program and save the file with a .c extension. For example, my_program.c. Step 2: You compile the program and generate the object file using gcc compiler in a terminal like this:

      gcc -o my_program my_program.c

      

      This was just a quick summary of how to compile and run a C program in Linux. If you are new to either C or Linux, I’ll show these steps in detail to make you comfortable coding C programs in a Linux environment. I’ll discuss how to run C programs in a Linux terminal and a code editor.

      Method 1: How to run C programs in a Linux terminal

      In order to run a C program in Linux, you need to have a C compiler present on your systems. The most popular compiler is gcc (GNU Compiler Collection). You can install gcc using your distribution package manager. In Debian and Ubuntu-based Linux distributions, use the apt command:

      Switch to the directory where you have kept your C program (or provide the path) and then generate the object file by compiling the program:

      gcc -o my_program my_program.c

      Keep in mind that it is optional to provide the output object file (-o my_program). If you won’t do that, an object file named a.out will be automatically generated. But this is not good because it will be overwritten for each C program and you won’t be able to know which program the a.out object file belongs to. Once your object file is generated, run it to run the C program. It is already executable. Simply use it like this:

      And it will display the desired output if your program is correct. As you can see, this is not very different from running C++ programs in Linux.

      Every time you make a change in your program, you have to compile it first and then run the generated object file to run the C program.

      Method 2: How to run C programs in Linux using a code editor like Visual Studio Code

      

      Not everyone is comfortable with the command line and terminal and I totally understand that. You can use a proper C/C++ IDE like Eclipse or Code Blocks but they are often too heavy programs and more suitable for large projects. I recommend using an open-source code editor like Visual Studio Code or Atom. These are basically text editors and you can install add-ons to compile and run programs directly from the graphical code editor. I am using Visual Studio Code editor in this example. It’s a hugely popular open-source code editor from Microsoft. First thing first, install Visual Studio Code in Ubuntu from the software centre. For other distributions, please check your Linux distribution’s package manager or software centre. You may also check the official website for more information. Start Visual Studio Code and open/create a project and create your C program here. I am using a sample Hello World program. You must ensure the gcc compiler is installed on your Linux system.

      Next, you would want to use an extension that allows you to run the C code. Microsoft may prompt you for installing its own extension for the C/C++ programs but it is complicated to set up and hence I won’t recommend it. Instead, I suggest using the Code Runner extension. It’s a no-nonsense extension and you can run C and C++ code easily without additional configuration. Go to the Extensions tab, search for ‘Code Runner,’ and install it. Restart Visual Studio Code. Now, you should be able to run the C code by using one of the following ways:

      • Using the shortcut Ctrl+Alt+N.
      • Press F1 and then select or type Run Code.
      • Right-click the text editor and click Run code from the context menu.

      

      When you run the program, it is compiled automatically and then run. You can see the output in the terminal that is opened at the bottom of the editor. What could be better than this?

      

      Which method do you prefer?
