How to Run C Code on Fedora Linux

Running C code on Fedora Linux is a straightforward process. This guide will walk you through the essential steps, from installing the necessary software to writing, compiling, and running your C programs.

Step 1: Install a C Compiler

Fedora typically comes equipped with the GNU Compiler Collection (GCC), which includes the C compiler. You can install this package using the following command in your terminal:

sudo dnf install gcc-c

Step 2: Write Your C Code

You can use any text editor to write your C code. A common simple program you could write is the 'Hello, World!' program. Here's an example of how to write and save this code:

include iostream int main() { std::cout "Hello, World!" std::endl; return 0; }

You can create and edit this file using various text editors such as nano or vim. For instance, you can use nano as follows:

nano myprogram.cpp

Step 3: Compile the C Code

Once you have written your C program, the next step is to compile it. Use the g command followed by the filename to compile your code:

g myprogram.cpp -o myprogram

This command compiles your myprogram.cpp file and creates an executable file named myprogram.

Step 4: Run the Executable

To run your compiled program, simply type the following command in your terminal:

./myprogram

This should output:

Hello, World!

Summary

To summarize, here are the key steps you took to run C code on Fedora:

Install the compiler: sudo dnf install gcc-c Create a C program file (e.g., myprogram.cpp) Compile the program using g filename.cpp -o outputname Run the program using ./outputname

Frequently Asked Questions

Question 1: What if I don't have the necessary permissions to install software?

Use sudo to gain the necessary permissions. If you're still encountering issues, consult your system administrator or refer to the official Fedora documentation.

Question 2: Are there any alternatives to the terminal for managing C programs on Fedora?

Yes, you can use graphical IDEs like Code::Blocks, Geany, or Eclipse. These IDEs provide a more user-friendly interface for writing, compiling, and running C programs.
