C programming language is widely used in the world of computer programming due to its efficiency and versatility. Whether you are a beginner or an experienced programmer, understanding the steps involved in creating and running C programs is essential.
In this article, we will walk you through creating and running a C program utilizing an online C compiler. Additionally, we will include the essential header file “stdio.h” to enable input and output operations.
So, without further ado, let’s get started!

Steps of Creating and Running C Programs by Utilizing an Online C Compiler
Step 1: Choose an Online C Compiler
To get started, you must choose an online C compiler that allows you to write, compile, and execute C programs directly from your web browser. Several online platforms provide C compilers, such as ideone.com, repl.it, and tutorialspoint.com.
Step 2: Open the Online C Compiler
Open your preferred web browser and navigate to your preferred compiler’s website. Look for the “Online C Compiler” section or use the search bar to find it quickly. Click on the link to access the compiler.
Step 3: Create a New File
Once you have accessed the online C compiler, you will typically find a text editor area where you can write your C code. Start by creating a new file. To include the necessary input/output functionalities, add the following line at the beginning of your code:
#include <stdio.h>The “stdio.h” header file contains functions and macros for input and output operations such as “printf” and “scanf“.
Step 4: Write Your C Code
After including the “stdio.h” header file, you can start writing your C code. The code can range from a simple program to complex algorithms, depending on your requirements. For illustration purposes, let’s consider a simple “Hello, World!” program. Write the following code in the editor:
#include <stdio.h>
int main() {
printf("Hello, World!\n");
return 0;
}This program prints the text “Hello, World!” on the console.
Step 5: Save and Compile the Code
Once you have written your C code, it’s time to save the file. Most online C compilers provide a way to save the code by clicking a “Save” button or using a keyboard shortcut. Save your file with an appropriate name and the “.c” extension.
After saving, you can proceed to compile the code. In the online C compiler interface, there should be a “Compile” or “Run” button. Click on it to initiate the compilation process. The compiler will check for any syntax errors in your code.
Step 6: Fix Syntax Errors
If the compiler encounters syntax errors in your code, it will display error messages indicating the line and nature of the error. Review the error messages carefully, identify the issues, and correct them. Syntax errors are common, especially when learning or experimenting with new concepts.
Step 7: Run the Program
Once your code is error-free, it is ready to be executed. Click the “Run” or “Execute” button in the online C compiler interface. The program will start running, and the output will be displayed in the output console.
In the case of our “Hello, World!” program, the output will be:
Hello, World!
Congratulations! You have successfully created and run your first C program.
Step 8: Test and Modify
After running your program, you may want to test different scenarios or modify the code to achieve desired results. You can experiment by adding new functionality, implementing algorithms, or taking user input. Remember to save your changes and recompile the code to ensure it runs correctly.
