How To Use Online GDB Compiler? | Free Compiler and Debugger

Coding can be a lengthy and tricky process, making it easy to overlook compilation errors that can impact the quality of the outcome. That is why development tools have been introduced to streamline the process and improve code quality. OnlineGDB is one of the most popular online compilers and debugging tools. It is beneficial for programmers learning a new programming language, and they want the coding process to run more smoothly and quickly. This article will focus on the online GDB compiler and how to use it to make complex coding processes easy and improve code quality.

What is an Online GDB Compiler?

The Online GDB compiler is a compiler and debugger for widely used programming languages, including C, Python, Java, PHP, Ruby, Perl, and others. It is a very complex and exceptionally fast compiler that accepts and delivers results quickly. This can also be utilised to execute web development languages such as HTML, CSS, JavaScript, and SQL.

The new release of the GDB Compiler is 13.1, which includes the GNU debugger and can be downloaded from the online GDB Compiler site.

Online C Compiler

The C programming language is a general-purpose language developed by Dennis Ritchie to create system applications that would interact with hardware devices directly. C programming language is the core and base for other programming languages and hence, is considered to be the mother language. C language is used mostly for developing software and it is easy to write. Using C programming language to execute an application is better because its execution speed is faster than other programming languages.

The process of compilation is basically converting source code into object code, which is done with the help of a compiler. The function of the C Compiler entails converting the pre-processed code into assembly code.

With the online GDB compiler, you can access the online C Compiler and easily use it to run the C program online.

How To Access Online C Compiler in Online GDB Compiler?

Online GDB compiler have made it easy to code, compile, or run C programmes online. Read the following steps to learn how to access C Compiler in Online GDB:

Step 1: Go to Online GDB’s website and open it.
Step 2: Once it is open, find the Language selection section on the top right side of the page.
Step 3: Click on the “Select” button and choose the C programming language.
Step 4: Input the code on the black screen.
Step 5: Select “Run”, “Debug”, “Stop”, “Save,” and more as required from the top section, and perform all the necessary steps accordingly.

Attributes of the Online GDB Compiler

Some of the common attributes of the online GDB compiler are listed below:

It is the first online IDE with an integrated gdb debugger for debugging.
Everything functions well in the browser. With simple internet connectivity, you can code whenever and wherever you want.
It is a helpful web tool for developers who want to code online.
The platform is stable and does not fail suddenly.
Discover tricky flaws in your code with online GDB’s debugging capabilities.
From any device and location, you can develop, build, execute, and debug online.

The IDE has various options to improve productivity. Some of the available options are:

NEW File: Allows for the upload of a new file to the integrated development environment.
Upload File: This allows you to upload existing code or a programme from your computer to the IDE.
Run: The developer can use this method to execute their code and observe the results in real time.
Debugging: Debugging is a beneficial tool that allows programmers to detect and rectify problems in their code. The debugging feature enables the programmer to view and adjust the software while it is in operation.
Stop: The stop function allows the programmer to halt the software while it is operating to analyze and fix faults.
Share: The sharing tool allows developers to rapidly share their code with others. This tool can help developers collaborate with colleagues and receive feedback on their work.
Save: The save function allows the programmer to store their work for future reference.
Beautify: The beautify functionality allows coders to improve the readability and layout of their code. This option can assist in making the code more aesthetically pleasing and simpler to understand.

In addition to these functionalities, an IDE provides several other options to help developers be more productive. Auto-complete and code suggestion capabilities can help developers write code faster and with fewer mistakes. Code analysis and enhancement tools can help identify performance constraints and optimise code for increased performance. Integrated version control solutions can help developers manage code versions and collaborate effectively with others.

Basic GDB Commands and Debugging Concepts

Some of the basic GDB commands and debugging concepts have been provided below:

To begin using GDB, first compile the program using the -g option, which enables GDB debugging capabilities. Once the code has been developed, it can be launched in GDB by typing “gdb” followed by the program’s name.
The “breakpoint” is an essential GDB feature that allows programmers to halt the program’s execution at a specified point in the code. Add breakpoints by using “break,” followed by the name of the function or file and the line number where the breakpoint should be placed. The programme can then be executed using the run command, and GDB will stop it when it reaches the breakpoint.
To start using GDB, the first step is to compile the code with the -g option, which facilitates debugging support for GDB. Once the programme is compiled, it can be directed in GDB using the gdb command followed by the name of the program.
The breakpoint allows programmers to stop the program’s execution at a specific point in the code. Breakpoints can be set using the break command, followed by the name of the function and the line number where the breakpoint should be set. The programme can be run using the run command, and GDB will stop the program’s execution when it reaches the breakpoint.
After the programme has been stopped at a breakpoint, coders can examine the program’s state and find problems. The print command shows the value of an expression, while the step and next statements allow programmers to move through the programme execution line by line.

How to Use the Online GDB Compiler?

Mentioned below are some ways you can use the online GDB compiler:

The online GDB compiler is a comprehensive tool that supports over twenty popular programming languages, making it a viable solution for developers of all skill levels. You can work on programming languages, including CSS, HTML, C, Java, and Python. Select your coding language from the language menu on the right side of the command bar.
Some parameters in the online GDB compiler can improve the development experience. For example, while working on the compiler, search for the “I” icon on the right side of the command bar to obtain information about the gdb compiler shortcuts. This feature can help developers learn and use shortcuts to operate more effectively.
The settings option is another crucial feature of the online GDB compiler. This feature, accessed by selecting the settings button, allows the programmer to customize numerous compiler parameters. You can adjust the editor theme, font size, tab space, and other parameters to make the interface more user-friendly and productive.

Sample program to show “Good morning, Have a blissful day”

// Sample Good morning program

#include <stdio.h>

int main() {

// printf() indicates the string inside the quotation

printf(“Good morning, Have a blissful day!”);

return 0;

}

Click the green “Run” button to compile and execute your C

Output

Good morning, Have a blissful day!
