C is a popular and widely used programming language that is commonly used for system programming and low-level programming. Writing a Hello World program is a great way to get started with learning the basics of C programming.
Here's a step-by-step tutorial to help you write your first Hello World program in C:
Before you start writing your C program, you need to set up your development environment. You'll need a text editor to write your code, and a compiler to compile and run your program.
There are many text editors and compilers available for C programming, but some popular choices include Visual Studio Code, Sublime Text, and GCC.
Once you have your development environment set up, you're ready to start writing your program. Open your text editor and create a new file. In this file, type the following code:
#include int main() { printf("Hello, World!"); return 0; }
This code uses the printf function to print the text "Hello, World!" to the console.
Save your file with the name hello.c. Now, you arere ready to compile and run your program. Open a terminal window and navigate to the directory where you saved your file.
Type the following command to compile your program:
gcc -o hello hello.c
This command compiles your program and creates an executable file called hello.
Now, type the following command to run your program:
./hello
This command executes your program and displays the output "Hello, World!" on the console.
Congratulations! You have successfully written and run your first program in C.
In conclusion, writing a Hello World program in C is a simple yet powerful way to get started with programming in C. By following this step-by-step tutorial, you have learned how to set up your development environment, write C code, and compile and run your program. With this basic understanding of C programming, you are ready to start exploring the many other powerful features and capabilities of this popular programming language.
