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:
Step 1: Set up your development environment
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.
Step 2: Write your code
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.
Step 3: Compile and run your program
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.
