How to Run C program in Ubuntu

Learning to run a C program in Ubuntu is a great first step for anyone starting their programming journey or switching to a Linux-based system. Ubuntu offers a clean and powerful environment to write, compile, and execute C code all from the terminal.

In C, this guide will show you how to get started. From writing your first C program to compiling and running it in the Ubuntu terminal, we’ll cover everything you need in simple steps.

How to Run C Program in Ubuntu?

To compile and run a C program on the Ubuntu operating system via a file, we require the GCC compiler in our internal system. One of the build-essential packages that produces the various activities that we need to install from the Ubuntu repository is the GCC Compiler.

We must develop our C program in an Integrated Development Environment (IDE) like Visual Studio Code or a basic text editor which can compile and run all of the programs after installing the build-essential package. We must then compile and run our C program by creating a file on the terminal. Follow the below-mentioned easy steps to run and compile a C program in Ubuntu.

Step 1: Install GCC compiler on Ubuntu

• Install the GCC compiler on the Ubuntu operating system > Check the GCC compiler installation status by using the below command

$ gcc -version

Step 2: Implement touch command

• Use the touch command on the terminal > Create a C program file

$ touch hello.c

Step 3: Write a C program on the file

• Open the file named hello.c > Write a basic C program

Let's see the hello.c program -

#include <stdio.h>

int main() {

    // code
  printf("Hello world");
    return 0;
}

Hello world

Step 4: Compile the hello.c program

• Go to the program file > Compile hello.c file
• Use gcc hello.c command in the terminal > Generate hello executable file in the Ubuntu system terminal

Step 5: Run the hello executable file

• Use ./hello command in the environment > Run the hello executable file in the terminal on Ubuntu

Now, we can see the actual output of Hello World in our terminal of the hello.c system file.

Conclusion

For executing Linux-based applications, Ubuntu is a popular Linux-based operating system in today's technology. In addition to offering an adaptable and open-source platform for a variety of internal applications and professional industries, it allows all users to customize the system. All we need to do is write our C program in a text editor create a file, compile it, and run it in the terminal after installing the build-essential package by following the proper steps. This simple procedure enables all the users to begin using C programming in Ubuntu.
